I have a built 305 in my truck that the PO had done. I don't have any specs but from what I can tell it has 327 dubble hump heads, performer intake, 600 carb, headers, Accell dis, and a BIG

cam! I don't know the size of the cam but it seems to be pretty big. I can't sit at a stop light in drive and It won't turn a tire from a dead stop, it really starts to run about 3000 rpm. based on the other stuff and without knowing the compression ratio what should be a good cam for my motor. The motor seems solid but that big of a cam seems like over kill in a 305.
