A value-priced 350 with 330 horsepower!

This engine doesn't sacrifice power or durability. With its four bolt main block, nodular iron crankshaft, PM steel connecting rods and light but strong cast aluminum pistons, this engine screams durability. Add to the strong foundation a pair of 64cc Vortec cast iron cylinder heads with 1.94'' intake and 1.50'' exhaust valves which yields a healthy but streetable 9.1 to 1 compression ratio, and you've got the small block that you need for that muscle car or street rod project. The camshaft is a modern dual pattern interpretation of the old '65 to '67 Corvette 327 cam. But with more lift and duration on the exhaust side for clearing the combustion chamber better. While the intake duration and lift was decreased slightly to build more cylinder pressure. This engine features chrome valve and timing covers, plus the oil dipstick is located on the right side.
