Musi Pump gas 555
Musi sells a crate Chevy 555 touted as big power at 676 -723hp runs on 91 octane.
This seems very doable on a 555 Pontiac with 350 cfm e-heads.
What do you guys think?

Paul would larger headers mask a poor cam selection?
Meaning, if the cam is not correctly spec'd would larger headers add more power.
