This special performance 350CI/330 HP engine has a modest 9:1 compression ratio. It is ideal for today's street machines, with performance of the 1960s and fuel availability of the 1990s 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, carburetor, etc. Requires the use of Vortec intake.

TECHNICAL INFORMATION: Horsepower: 330 @ 5000 rpm Torque (ft./lbs.): 380 @ 3800 rpm Maximum rpm: 5500 Compression ratio: 9:1 Cast-iron block with 4-bolt main caps Nodular iron crankshaft Connecting rod: Powdered metal steel Cast aluminum pistons Camshaft-type: Hydraulic flat tappet Lift (in): .435 intake/.460 exhaust Duration (@.050 in): 212° intake/222° exhaust Cylinder heads: Vortec iron; 64cc chambers Valve size (in)- intake: 1.94 exhaust: 1.50 Stamped steel rocker arms Rocker arm ratio: 1.5:1 Ignition timing: 10° BTDC @ 700 rpm IMPORTANT: Requires the use of an 1986 or newer counter-weighted flywheel.
