I only got interested because its the COMBO that I want to run!
1971 sixpack 'all-iron' engine with a sixpack, exhausting through them AWFUL HP manifolds... blah

So will someone out there PLEASE tell me the BEST COMBO???

Basically what I'm saying, who's got the best 'ALL-IRON' set-up, WITH HP manifolds and what's the CAMSHAFT choice...???

Obviously the 'supposed' SIXPACK naughty Nick was running, was a POO motor with low comp pistons, 516 heads (probably) and a lumpy 'OLD SCHOOL' cam... fan
"best all iron set-up"? best would be race gas. pump gas being more practical for dual purpose. i think the most economical pump gas would have a good set of heads (i'd use KB184 pistons for open chamber), something like a summit 6401 cam, straight thru mufflers, and not over geared or over converter. race gas would open things up some power wise but would be a higher cost.
