The 350 HO Deluxe takes the value leading 350 HO a step further by adding carburetor, distributor, water pump, torsional damper, and auto trans flexplate. This enhancement to the Vortec cylinder head 330 horsepower 350 HO makes it easier than ever to repower your street rod, street machine or sportsman racer. The 600 cfm vacuum secondary Holley carburetor is ideally suited to the 350 HO. And the proven GM HEI distributor will give years of worry-free driving. With a 9.1 to 1 compression ratio, it’s pump gas friendly, and with its muscle car idle it’s cruise night cool. With GMPP’s lowest priced small-block crate engine there is no reason to rebuild that junk yard clunker and since it’s complete from carb to pan there is no need to chase parts. Talk to your GM Performance Parts Authorized Dealer about any additional required parts to complete your re-power project. This engine is perfect for your 1975 or older vehicle or any off-road usage.
