More Details on Our Top Picks

  1. GM Parts 12568758 Crate Engine for GM Truck 350

    GM Parts 12568758 Crate Engine for GM Truck 350

    Best Budget-Friendly Option

    View Latest Price

    This engine stands out for its affordability and compatibility with GM trucks, making it a solid choice for budget-conscious restorers and those restoring vintage trucks. Compared with more powerful options like the BluePrint 383 or the Chevrolet Performance ZZ6, this model offers less horsepower but maintains reliable performance for daily driving or light-duty use. Its 2-bolt main design and rear seal are standard features that keep costs down but limit high-performance potential. The engine’s simplicity and lower weight make it easier to install, especially for DIY enthusiasts. However, it’s not ideal for high-horsepower builds or marine applications, where more robust components are required. This pick makes the most sense for buyers seeking a dependable, cost-effective engine for stock or lightly modified vehicles.

    Pros:
    • Affordable price point for a genuine GM crate engine
    • Compatible with a wide range of GM trucks and classic vehicles
    • Easy to install with standard mounting and rear seal design
    Cons:
    • Limited horsepower and torque compared to performance engines
    • 2-bolt main design restricts high-revving or high-stress applications
    • Not suitable for marine or racing use

    Best for: Budget-conscious restorers and owners of vintage GM trucks needing a reliable, straightforward crate engine.

    Not ideal for: Performance builders or marine applications, due to its basic design and intended use limitations.

    • Displacement:350 cubic inches
    • Engine Type:2-bolt main, rear seal
    • Legal for Sale in CA:Yes
    • Intended Use:Truck, stock replacement
    • Marine Use:No

  2. BluePrint Engines Compatible with GM Small Block, 383 c.i. Engine – 436 HP – Base Dressed – Fuel Injected

    BluePrint Engines Compatible with GM Small Block, 383 c.i. Engine - 436 HP - Base Dressed - Fuel Injected

    Best Performance Value for a 383 Stroker

    View Latest Price

    This engine makes a compelling case as the best value for a 383 stroker build, especially when compared with the 350 cubic inch options. It delivers 436 HP and 443 ft-lbs of torque, which surpasses the stock 350 engines like the GM Parts 12568758. The inclusion of aluminum cylinder heads and a hydraulic roller cam offers a significant boost in power and efficiency, suitable for street or mild race applications. Its cast iron block, 4-bolt main, and steel crank ensure durability for high-performance use. The downside is that it’s a highly specialized build, requiring extra tuning and potentially higher installation costs. For those who want a robust, fuel-injected stroker that balances power and reliability, this engine hits the sweet spot. However, it’s less suited for marine use due to its fuel injection setup and non-marine certification.

    Pros:
    • High horsepower and torque output surpasses stock engines
    • Includes aluminum cylinder heads for better airflow and efficiency
    • Durable cast iron block with 4-bolt main for high-stress use
    • Factory assembled and Machined in the USA
    Cons:
    • Requires advanced tuning and installation expertise
    • Engine package does not include fuel pump or accessories
    • Potentially higher cost compared to basic crate engines

    Best for: Performance-minded street enthusiasts seeking a powerful, reliable 383 stroker engine with fuel injection.

    Not ideal for: Marine applications or buyers looking for a simple, carbureted engine with minimal modifications.

    • Horsepower:436 HP
    • Torque:443 ft-lbs
    • Displacement:383 cubic inches
    • Block Material:Cast iron
    • Main Caps:4-bolt
    • Cylinder Heads:Aluminum
    • Cam Type:Hydraulic roller
    • Bore:4.000 inches
    • Intake:Fuel injection

    Bottom line: This engine is best suited for street enthusiasts who want a high-performance, fuel-injected 383 stroker with great power reserves.

    BluePrint Engines GM Small Block Compatible 400 c.i. Engine - 500 HP - Long Block

    Best High-Horsepower Long Block

    View Latest Price

    This 400 cubic inch long block from BluePrint Engines is designed for serious performance, offering 500 HP and 500 ft-lbs of torque, making it ideal for high-powered street or drag racing builds.

The 4-bolt main and internally balanced design add reliability for high-RPM operation. Compared with the 383 stroker, this engine provides more displacement and power, but it is also heavier and more complex to install. Its manufacturing in the USA ensures quality, but the weight and complexity might be overkill for casual street drivers. This engine suits buyers seeking a long-term, high-horsepower solution, but less so for those on a tight budget or with limited space in their vehicle.

    Pros:
    • Impressive 500 HP and 500 ft-lbs torque output
    • Forged steel crank and pistons for durability
    • Aluminum cylinder heads for high airflow
    • Manufactured and machined in the USA for quality
    Cons:
    • Heavy weight complicates installation and handling
    • Long block requires additional components for complete setup
    • Higher cost due to high-performance features

    Best for: High-performance street or drag racers requiring a powerful, durable long block with substantial displacement.

    Not ideal for: Casual street drivers or those preferring carbureted setups, due to its long block design and high weight.

    • Horsepower:500 HP
    • Torque:500 ft-lbs
    • Displacement:400 cubic inches
    • Main Cap:4-bolt
    • Block Material:Cast iron

    Chevrolet Performance Crate Engine

    Best Ready-to-Install High-Performance Crate Engine

    View Latest Price

    This engine from Chevrolet Performance offers a straightforward, high-performance solution designed for enthusiasts who want a ready-to-install unit. Weighing 485 lbs with dimensions of 43.5″ x 34.38″ x 31.38″, it is built in China, which may concern buyers preferring domestic manufacturing. Its heavy weight means it requires proper lifting and installation equipment, but it’s built for durability and consistent performance. Compared to the BluePrint or other aftermarket options, this engine emphasizes reliability and ease of use over maximum customization. It’s ideal for those who want a high-performance engine without the fuss of a custom build, but it’s less attractive for buyers seeking a purely domestic product or lightweight setup.

    Pros:
    • High-performance engine from Chevrolet Performance
    • Durable construction with heavy-duty components
    • Ready-to-install with minimal setup
    Cons:
    • Manufactured in China, which may not meet some buyers’ preferences
    • Heavy weight requiring specialized lifting tools
    • Dimensions may complicate installation in smaller engine bays

    Best for: Performance enthusiasts looking for a dependable, bolt-in crate engine with minimal fuss.

    Not ideal for: Budget buyers or those preferring domestic-made engines, due to its Chinese manufacturing and weight.

    • Country of Origin:China
    • Package Quantity:1

    View Latest Price

    Offering a balanced mix of power and reliability, this 383 cubic inch long block from BluePrint delivers 436 HP and 443 ft-lbs of torque, making it suitable for a variety of street and mild race builds. Its forged steel crank, hypereutectic pistons, and aluminum heads provide durability and good airflow at a reasonable price point. It compares favorably with the 350 engines in the lineup, providing significantly more displacement and power. The internal balance and 4-bolt main add to its reliability under high-stress conditions. The complexity lies in its long block design, requiring additional components for a complete setup.

    View Latest Price

    This engine stands out for delivering a robust 436 HP and 443 ft. lbs. of torque, making it ideal for those seeking maximum performance in a crate engine. Compared with the BluePrint 350 c.i. engine, it provides significantly more power, though it does involve a higher weight and potentially more complex installation. Its aluminum cylinder heads and hydraulic roller cam translate to excellent high-end responsiveness, perfect for enthusiasts wanting both street and strip capability. The true 4-inch bore and steel crankshaft ensure durability, but the engine’s size and lack of OEM compatibility could pose challenges for certain builds.

Compared with the 350 version, it provides significantly more torque and slightly more horsepower, thanks to its larger bore and optimized components. Its aluminum heads and hydraulic roller cam ensure high-end responsiveness, ideal for street and strip use. However, its size and weight—around 475 pounds—may challenge some OEM applications, and it is not compatible with pollution-controlled vehicles. This engine makes the most sense for enthusiasts seeking a high-performance street build with some room for tuning.
    Pros: 436 HP and 443 ft. lbs.; High-quality aluminum heads; Durable cast steel crank; True 4-inch bore for extra displacement.

    This 350 c.i. engine produces 341 HP and 371 ft. lbs., offering a dependable and cost-effective solution for daily driving and restoration projects. Compared to the 436 HP 383 engine, it provides lower horsepower but benefits from lighter weight and easier OEM compatibility, making it suitable for stock rebuilds. Its hypereutectic pistons and cast iron block ensure longevity, and the carbureted setup simplifies tuning. Nonetheless, its weight of around 534 pounds can make installation more challenging, and it lacks the extra power some performance builders desire. This engine makes sense for budget-conscious buyers needing a reliable, factory-style replacement.
    Pros: Affordable price point; Reliable 341 HP; Good OEM compatibility; Proven durability.
    Cons: Heavy at 534 pounds; Lower power ceiling; No fuel injection option; Less suitable for high-performance modifications.

Compared to the custom 383 and 350 engines, the ZZ6 provides a high but consistent power output suitable for enthusiasts wanting a plug-and-play solution.

  11. DM21 Long Block Marine Crate Engine for Chevy 350

    DM21 Long Block Marine Crate Engine for Chevy 350

    Best Marine-Specific Chevy Crate Engine

    View Latest Price

    This marine long block stands out for its tailored design for boating applications, featuring special marine pistons, rings, and camshaft that ensure optimal performance on water. Compared to standard Chevy crate engines like the GM Parts 12568758, this model incorporates marine-grade components that resist corrosion and handle high humidity environments, making it ideal for boat engines. However, this focus on marine durability means it’s heavier—at 420 lbs—and less suitable for street or off-road use. Its cast iron construction guarantees long-term durability, but the specialized marine parts come at a premium, and installation may require additional marine-specific accessories. This pick makes the most sense for boat owners needing a reliable, water-resistant engine.

    Pros:
    • Tailored marine pistons and camshaft for water resistance
    • Heavy-duty double-roller timing chains for durability
    • Marine gaskets and valves resist corrosion and high humidity
    Cons:
    • Heavier weight of 420 lbs limits ease of handling and installation
    • Higher cost due to marine-specific components

    Best for: Boaters seeking a durable, water-ready engine with long-term marine performance.

    Not ideal for: Street car owners wanting a lightweight, high-performance engine for daily driving or racing, as this engine is heavier and specialized for marine use.

    • Engine Displacement:350 Cubic Inches
    • Engine Type:4 Stroke
    • Mounting Type:Engine Mount
    • Fuel Type:Gasoline
    • Material Type:Cast Iron
    • Weight:420 lbs

    Bottom line: This engine is best suited for boat owners who need a water-resistant, durable powerplant that can withstand marine conditions.

How We Picked

Our evaluation focused on a combination of performance, build quality, versatility, and value. We compared horsepower ratings, compatibility with common Chevy builds, and the level of assembly required—dressed versus long blocks. Cost was also a key factor, ensuring options cater to different budgets. To ensure relevance, we prioritized engines with proven reliability and positive user feedback, ranking them based on overall bang for the buck and suitability for various project types.

Factors to Consider When Choosing Best Chevy Crate Engines

Choosing the best Chevy crate engine involves more than just horsepower figures. Buyers need to consider compatibility with their vehicle, intended use, and budget. Understanding these factors can prevent costly mistakes and help select an engine that delivers both performance and value. The following sections highlight key considerations to keep in mind before making a purchase.

Performance and Power Ratings

Horsepower and torque are primary factors, but matching these specs to your vehicle and intended use is essential. For example, a high-horsepower engine like the ZZ6 is ideal for muscle car projects, while a more moderate option like the GM Parts 12568758 suits daily drivers or trucks. Overestimating power needs can lead to unnecessary costs, whereas underestimating can limit your vehicle’s capabilities. Always consider your performance goals alongside your budget to find the best fit.

Dressed vs. Long Block Engines

Dressed engines come with accessories, manifolds, and other components installed, saving installation time and effort. However, they typically cost more upfront. Long blocks, on the other hand, provide the core engine without accessories, offering flexibility for custom setups or specific configurations. Understanding your mechanical skill level and project scope will help determine whether a dressed or long block engine makes more sense for you.

Intended Use and Application

Your engine choice should reflect how you’ll use your vehicle. Marine engines like the DM21 Long Block Marine Crate Engine are optimized for watercraft, with corrosion-resistant features. Street performance engines prioritize horsepower and smooth operation, while truck engines emphasize torque and durability. Clarifying your primary application helps narrow down options and avoid overpaying for features you don’t need.

Budget and Long-Term Value

Affordable options like BluePrint Engines often deliver excellent value, especially for rebuilders or hobbyists. However, spending more on a premium engine like the ZZ6 can provide better longevity and performance for daily drivers or high-performance builds. Consider not just the initial cost but also the expected lifespan, maintenance requirements, and potential upgrades to determine the best long-term investment.

Compatibility and Installation Considerations

Ensure the engine physically fits your vehicle and matches its mounting points, accessories, and emissions requirements. Some engines require additional components or modifications, adding to the overall cost and complexity. Double-check compatibility with your existing transmission, cooling system, and exhaust setup. Investing time upfront to verify these details can prevent frustrating surprises during installation.

Frequently Asked Questions

How do I choose the right horsepower for my Chevy crate engine?

Selecting the correct horsepower depends on your vehicle’s current setup and your performance goals. For street driving or daily commuting, moderate horsepower ratings around 300-400 HP are usually sufficient. If you’re building a high-performance street machine or drag car, higher ratings above 400 HP may be necessary. Consider your transmission, rear-end gearing, and intended use to find a balanced configuration that offers enough power without sacrificing drivability.

Are dressed engines worth the extra cost?

Dressed engines can be a worthwhile investment if you want a quicker, less complicated installation since they come with accessories like alternators and water pumps already installed. However, they cost more initially, and sometimes their components may not match your preferred setup. If you’re comfortable with assembly or need a custom configuration, a long block might provide better value. The decision hinges on your mechanical skill and project timeline.

Can I install a marine crate engine in a street vehicle?

Marine engines are designed for watercraft and may include features like corrosion-resistant components that are unnecessary in street vehicles. While technically possible, they might require modifications to fit your application and meet emissions standards. For most street applications, choosing an engine designed specifically for automotive use ensures better compatibility, easier installation, and compliance with local regulations.

How much should I budget for installation and accessories?

Installation costs vary widely depending on your mechanical experience and the complexity of your project. Expect to spend additional on accessories, mounting hardware, and possibly custom wiring or exhaust components. Budgeting at least 10-20% of the engine’s cost for installation and ancillary parts is a good rule of thumb. Planning ahead can prevent unexpected expenses and ensure your build stays on track.

Is it better to buy a new crate engine or rebuild my existing one?

Deciding between a new crate engine and rebuilding your current motor depends on its condition and your goals. A new crate engine offers reliability, warranty coverage, and often better performance, making it suitable for most rebuilds or swaps. Rebuilding can be cost-effective if your existing engine is still in good shape but may involve more time and risk. Evaluate your engine’s condition and your mechanical skills to determine the best route.

Conclusion

The ideal choice varies based on your specific needs. For a reliable, all-around performer, the GM Parts 12568758 makes a solid choice for daily drivers and trucks. The Chevrolet Performance ZZ6 stands out as the best for those seeking maximum horsepower and high-performance builds. Budget-conscious buyers will appreciate the value offered by BluePrint Engines, especially for custom projects. Beginners or casual enthusiasts should consider engines with straightforward installation and good support, while experienced builders might prefer long blocks for maximum customization. Clearly, your project goals and budget will guide the best fit among these top options.
