225 head pipe

Unfortunately just opening up the exhaust system on a slanty is not going to wake them up from the dead.

Unless you go high compression and cam like Rusty did.

Had the '78 225 factory 2 bbl setup and the '76 225 1bbl with the best factory cam. No comparison when going to stock 318 with a 4 bbl. Night and day difference, I know I tried. 2 totally different vehicles going from a slanty to a V8.

Wish it were different, the slanties will stretch your mpg though.
