Street and Race Performance In One Package!

This is the engine of choice for many street rods, drag racers, and show cars. With 355 HP and 405 ft.lbs. of torque, this small block aluminum head engine gives you alot of bang for your buck. Starting with a 4-bolt main block, undercut rolled /forged steel crankshaft, PM Steel connecting rods and high silicon aluminum pistons w/ offset pins, you start to understand how over 400 ft.lbs. of torque is generated. Add to the mix angle plug aluminum cylinder heads with 58cc combustion chambers and 1.94'' int./ 1.50'' exh. valves and you get a responsive 10 to 1 compression ratio. And helping this combination breathe is a steel hydraulic roller tappet camshaft with .474'' int./.510'' exh. lift that has just enough lope for that muscle car sound.
