The 350 HO Deluxe takes the value leading 350 HO a step further by adding carburetor, distributor, torsional damper, and 12.75in 153 tooth automatic 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.
