headers vs manifolds on a 318 2bbl difference ????

That would make for a nice drivable street combo.

Thanks. It’s a proven kind of combo dispite what others claim is not doable. Which amazes me. But! It’s the internet and even though YOU sat in the dyno room testing your engine a dozen plus times, there’s always some asshole telling you your wrong and there’s no way the engine can do that.

I built my wife’s Barracudas roller 360 with this basic idea of a combo. 11-1 & a short duration roller cam with some decent lift. While it’s not a 1/4 mile screamer with 3.55’s, it’s easy to swap gears on the 8-3/4.

As it is, the top end just keeps on going and going and going.
