I have a 87+ 350 engine with roller cam setup. I have the quadrajet carb, intake rpm intake manifold, vortec heads, hooker 2055 headers, gmmg exhaust and a 2700 stall convertor with corvette servos. I was wondering which roller cam i should go with as i will be using beehive springs. Also I am doing this as i swap out the 305 from my 85 z28. Is there a chip or ECM i should get?
