Description

Propel vintage Corvette sports cars with the Edelbrock 46410 Crate Engine. Displacing 5.7 liters across 350 cubic inches, this Performer Hi-Torq small block Chevrolet creates 363 horsepower at 5500 RPM and 405 lb-ft torque at 3800 RPM.

E-Tec 170 aluminum cylinder heads feature 64cc combustion chambers, setting dressed dry weight at 460 lbs.

Short Water Pump Hi-Torq Dyno Calibration

Dynamometer testing confirms 363 brake horsepower at 5500 RPM and 405 lb-ft torque at 3800 RPM across an operating band between 1500 and 5800 RPM. Cam duration measures 212 degrees intake and 222 degrees exhaust at 0.050 inch lift, producing 0.462 inch intake and 0.479 inch exhaust lift. The engine draws 16 in-Hg vacuum at 750 RPM on 91 octane fuel, holding 45 to 60 PSI hot oil pressure.

Corvette Short Pump Chassis Fitment Bounds

Standard small block Chevrolet dimensions drop straight into 1955 to 1982 Corvettes and vintage street rods without firewall modifications. The internal neutral balance crankshaft couples to classic GM TH350, 700R4, or manual four speed transmissions with standard bellhousings. The included short water pump preserves front fan clearance, while the installed oil pan clears steering drag links.

Retro Fit Roller Startup Safeguards

Pre prime the engine oiling channels with high zinc break in oil using an oil pump drive tool prior to startup. This street performance engine is not engineered for marine bilge setups, forced induction boost exceeding six PSI on stock ring end gaps, or uncalibrated nitrous kits.

• Drain break in oil and replace the spin on lube filter after the first 500 operating miles.
• Perform regular motor oil changes every 3000 miles or six months with high zinc synthetic oil.
• Inspect carburetor float adjustments and verify ignition timing advance every 6000 street miles.
