Product Details
The Chevrolet Performance 350ci HO Base Engine doesn't sacrifice power or durability with its four-bolt main block, nodular iron crankshaft, Powdered Metal steel connecting rods and cast aluminum pistons. Chevrolet engineers add to this strong foundation a pair of cast iron Vortec 64cc cylinder heads with 1.94'' intake and 1.50'' exhaust valves, yielding a healthy but streetable 9.0:1 compression ratio. The camshaft is a modern dual pattern interpretation of the 1965-67 Corvette 327 camshaft with more exhaust lift and duration for improved combustion chamber clearance and less intake lift/duration for more cylinder pressure!
