![]() |
88958604 GMR 350/400 Circle Track Engine Great racing power at a reasonable cost (400 HP at 5500 RPM - Torque 400 @ 4500 RPM)
This is a factory sealed crate engine package, complete from intake manifold, stamped steel valve covers with racing style
breathers, and 8 quart dual kick-out circle track racing oil pan. The Fast Burn 400 engine is a great value with the 1053
forged steel crankshaft, aluminum heads with 2.00”/1.55” valves, hydraulic roller lifters, and an HEI distributor.
GM uses the 385 horsepower Fast Burn 385 as the base for this engine.Technical Notes: These engines are sealed at the intake manifold, cylinder head, front cover, and oil pan with special twist off bolt heads. The 400 HP @ 5500 RPM was derived from a superflow dyno using a 4 barrel 650 cfm Holley carburetor P/N 80541-1, 32” long by 1-5/8” to a 1-3/4” stepped header with a 3” collector, and 92 octane unleaded gasoline. This engine package DOES NOT include a water pump. Oil pan clears most GM rear steer chassis with stock engine location. Oil pan is 7” deep at sump. |
