Re: 402 chevy big block
CR did drop to 8.5 to 1 in 1971....HP rating was 300 in 1971 and dropped to 240 in 1972. This engine was used in Chevelles, El Caminos, Camaros and full size cars. Also available in pickups....good platform to build on for a street car. A good set of oval port heads, a better cam and a little more compression will really wake it up.
