I am looking at a 1968 327 to put in the old truck.Trying to decide if it has 202 or 194 heads. It has the double hump casting marks a lowrise castiron manifold with a qjet. the damper pulley is not bolted to the crank. My guess is a 300 hp 327 with the 194 heads. my buddy hopes it is a 202 head so we can put a bigger cam in it and get the hp up.Any way to tell with out pulling the head? Thanks for any thoughts.
