I have a 454 out of a 1977 GMC high sierra. It has a turbo 400 behind it and i'm putting it in a 1977 Monte carlo with 3.73 posi rear end. I'm keeping the stock pistons since the engine only had 90,000 miles on it and they look good. also keeping stock head (going to have them port and polished). Carb will be a q-jet (don't laugh i have a guy that worked for GM that says he can rebuild and adjust it so there will be no hesitation off the line). The trans has 1000 miles on it and i'm putting in a b&m shift kit. Also adding headers. what i want to know is this. What size cam can i put in it with out adding a high stall converter? can i put in a hydrolic cam? roller rockers? I'm looking for idle to 5000rpm power. This is a summer driven only car. i take it to car shows up to 100miles away. some have drag races the night before the shows and i'd like to not look to slow. thanks for any advice. oh and i'm not doing the work my buddy is and i just want to check prices. thanks.
