Yea I am just curious on what people think, I’ve got 95% of the parts for the build. I’m about a month out from having it built. Kinda curious what it should make for boost

Leave the heads, cam, and exhaust stock. That will raise the boost level a lot.

I’m with this guy! Throw some 706 heads on it and leave the factory exhaust on with the factory cam! This should get ya around 12-14psi of boost!!!

but honestly you’ve got a really nice setup going on! Me personally, I’d went with a smaller cathedral port head, that’s the only change I would’ve made. The lower your boost numbers the better! Meaning, your motor is more efficient! Anyways when you get it all going, if you want higher boost numbers, just run a smaller pulley on the supercharger!
