88958604 GM 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 the intake manifold, stamped steel valve covers with racing style breathers to the 8 quart dual kick-out circle track racing oil pan. Because it is based in the 350 Fast Burn engine, the 350/400 racing engine includes the bulletproof bottom end anchored by a forged steel crankshaft and hypereutectic pistons.  The 23-degree, Fast Burn aluminum heads enable tremendous power in the small-block V8 because of a unique chamber design that quickly and completely burns all of the air/fuel mixture-giving you maximum power all the time.

The base engine is a Fast Burn 350ci 385 horsepower, with the following parts:
P/N 10105123 4 bolt iron block
P/N 14088533 1053 steel crankshaft
P/N 10108688 PM rod
P/N 10159436 High silicon aluminum piston
P/N 10185071 Camshaft with hydraulic roller lifters
P/N 12464298 Aluminum head
P/N 12496822 High rise single plane intake manifold
P/N 25534354 8 quart circle track oil pan (with oil filter)
P/N 25534359 Valve cover kit with breather tube
P/N 25534355 Valve cover breather kit
P/N 25534352 Special rocker arm nut "kool nut design"



Technical Notes:
These engines are sealed at the intake manifold, cylinder head, front cover, and oil pan with special twist off bolt heads. The Oil pan clears most GM rear steer chassis with stock engine location. Oil pan is 7" deep at sump.
