i'd have to agree, my 75 in its stock form was a real dog out of the hole, it was 165 h.p.
a 460 lift cam, headers, 2 1/2" exhaust,weiand excellerator intake , holley 680 d.p. msd ignition. it is only 1.95 / 1.6 valves though. the best guess i got for those mods was 325 h.p. max.mike

The highest stock specs were 185 hp for 1978. Emissions killed the HP output on the SBC in the 70's. My 1974 350 Vet only has 8.5:1 CR and that all by it's self limits the amount of HP it can make. Closed chamber heads will boost compression and everything else with help but your still limited.
