hi everyone,its been a good wile since i posted on this forum.im in the proces of rebuilding my 235 chevy, i been debating on running a offenhauser with a 2 carb set up and maybe some fenton headers. i was wonderig if anyone on here can give me a heads up on this set up. will it be a nightmare? are they really hard to tune n have running right? any info would help. thanks for your time.
