Caution: Carbureted engines can require more frequent tuning compared to modern engine management systems.
GM Small Block 350 c.i. Long Block
This long-block option for the small-block Chevy delivers 341 HP and 371 ft-lbs of torque. It uses aluminum cylinder heads and a hydraulic roller cam with a balanced valve train profile. The long-block approach is ideal for builders who want a solid foundation with fewer ancillary components to source.
- Power: 341 HP / 371 ft-lbs
- Heads: Aluminum Cylinder Heads
- Cam: Hydraulic Roller Cam
Best for: Builders seeking a straightforward upgrade path that focuses on core internals and a reliable baseline for further tuning. Better for those who want a clean, long-block starting point rather than a complete dressed engine.
Caution: This option may require additional dress components to achieve a full, ready-to-run configuration depending on project goals.
BluePrint GM Small Block 383 c.i. Fuel Injected – Base Dressed
This 383 c.i. engine comes base dressed with fuel injection, combining high horsepower with modern fuel management. It provides 436 HP and 443 ft-lbs of torque, along with aluminum cylinder heads for efficiency and a hydraulic roller cam. It’s a fit for drivers who want EFI performance without custom tuning.
- Horsepower & Torque: 436 HP / 443 ft-lbs
- Heads: Aluminum Cylinder Heads
- Cam: Hydraulic Roller Cam, .544/.555 Lift
Best for: Enthusiasts seeking EFI reliability and easier tuning across variable fuel conditions. Choose this if EFI performance is a priority over carbureted simplicity.
Caution: EFI systems may increase initial cost and complexity compared to carbureted equivalents.
BluePrint GM Small Block 383 c.i. Carbureted – Base Dressed
This 383 c.i. carbureted crate engine delivers 436 HP and 443 ft-lbs, packed in a base dressed configuration. It uses aluminum heads, a hydraulic roller cam, and a 10:1 compression ratio. It’s ideal for builders who want classic carbureted performance wrapped in a proven package.
- Power: 436 HP / 443 ft-lbs
- Heads: Aluminum Cylinder Heads
- Compression: 10:1
Best for: Carbureted builds that aim for raw, high-velocity power on the street or strip without EFI complexity. Avoid this if you require modern electronic fuel management from the start.
Buying Guide: Key Considerations For Your GM Small Block Crate Engine
- Engine type: Carbureted vs. Fuel Injected. EFI provides more consistent performance across conditions; carbureted setups are simpler and may suit traditional builds.
- displacement and power: Decide between 350 vs 383 c.i. options and match to vehicle weight and intended use (street, light racing, or show).
- Head design: Aluminum heads reduce weight and improve heat management; ensure compatibility with the block and other components.
- Camshaft profile: Hydraulic roller cam usually offers a good balance of performance and durability for street use; consider duration and lift for your rpm range.
- Compression: Higher compression improves power but may require premium fuel; lower compression improves reliability in varying fuels.
- Long block vs. dressed: A long block provides core internals with less dress; a dressed engine includes more peripherals for a ready-to-run package.
- Installation considerations: Vehicle compatibility, mounting patterns, accessory drives, and wiring harness compatibility affect install ease.
- Support and warranty: Manufacturer backing for BluePrint Engines can influence maintenance plans and future serviceability.
FAQ
- What is a crate engine? A crate engine is a complete, pre-assembled engine ready for installation with minimal in-house assembly required.
- Which is better for street use: carbureted or fuel-injected? EFI generally offers easier tuning, better drivability, and consistent performance across conditions; carbureted setups are simpler and can be preferred for classic builds.
- Are aluminum heads worth the extra cost? Yes for weight reduction and improved heat management, especially in lighter builds or high-performance applications.
- What does “dressed” mean in these engines? “Dressed” indicates the engine comes with many components installed and ready to install, though some ancillary parts may still be needed for full installation.
- What should I pair with a 383 c.i. engine for best results? A matching torque-friendly exhaust, appropriate camshaft, and a reliable fuel system (carb or EFI) based on your preference will optimize performance.
- Can I install these engines in a factory chassis? These engines are designed to be compatible with common small-block Chevy mounts, but verify fitment with your exact vehicle and drivetrain layout.
