Four New 15:1 Compression Ratio Starters Thursday, April 20, 2017

PROFORM 2.20 KW Starters for Ford (small & big block, 221-351W and 460 engines), Pontiac, Oldsmobile, and Buick 455s, offer faster engine turnover time, more clearance from the engine block, and an optimized gear-reduction design. These starters offer a 15:1 compression. As with all starters PROFORM produces, these Starters are 100% NEW, not rebuilt, for maximum longevity and optimum performance. After assembly, each starter is individually tested at the factory so enthusiasts need not use their vehicle as a testing lab.
