Building a 393 stroker to replace tired motor in 1991 F250 w/c6 trans. I plan on using edelbrock #3881 perfomer intake manifold with BBK 61 mm. I have an Anderson B21 roller hyd. cam I could use with 1.7 rockers. Need some suggestions on heads and if I should use another cam. I have read ejust enough to be on the verge of being confused. Concerned about compression being too high and need a head of 64cc or greater. I will be converting to MAF. Truck has 1-5/8 headers, 2-1/2 dual exhaust with twin delta 50 flowmwasters. The truck is used for "weekend warrior" runs to the dump and and hardware store.
