I know that, at a minimum, I'm looking at having to remove the head bolt boss and go with lump ports and larger valves. Probably a 600 cfm 4 barrel and certainly flat top pistons and headers. Would a stock GM HEI suffice for ignition?
What other mods would it take to get to 270 real HP (if it could be done)? | | |
