This special performance 350CI/330 HP engine has a modest 9:1 compression ratio. It is ideal for today's street machines, with the performance of the 60s and fuel availability of the 90s in mind. This budget-minded performer includes a 4-bolt main block, 64cc heads, hydraulic camshaft and forged connecting rods. It is delivered as a long block (with valve covers) leaving you with your choice of intake, exhaust, ignition, carb, etc. Requires the use of a Vortec intake.
IMPORTANT: Requires use of ’86 or newer counter weighted flywheel.
