okay i am a converted ford man , all i know about engines is sb ford. i have alot of questions about chevy sb engines. 1. i have a 400 cid in a 67 nova the timing seems to be advanced alot -maybe for the cam and large carb-but i don't have the typical setup on the distributor tower- no 3 & 4 facing front of motor-how is this possible? is there an old hot rod trick for relocating the distributor? 2.i have stock heads on the 400 now -what is a good choice head for this motor and i know i have to drill steam holes-how involved is this?3. the carb i have is a holley 12r10656 i'm not sure of the cfm but i think it is too much for this motor -any help would be appreciated.
any suggestions on the 400 cid set up (keep it driveable) would be helpful
