The specs on the test engine are as follows:


355 CID shortblock with approx. 10 to 1 CR (Note the AFR head had a slightly larger chamber volume netting less compression which was confirmed when each engine configuration was pump checked for cranking compression….the AFR headed combo pumped 15-20 PSI less depending on which cam was installed in the engine. The same CR would have made the results even more dramatic).

Comp Cams “Thumper” series cam grind # CS283T (227 deg / 241 deg @ .050 107 LSA)
Holley “Airstrike” dual plane intake manifold
Holley 750 CFM Carb
Hooker 1.75 dyno headers
