My buddy has a '97 grand am. He wants to do some mods, but there really isn't that much out there to boost performance. He'* wondering if he'd be able to swap on a W41 head? would it be a direct bolt up, and would it work?

is the 2.3 a quad 4?
i heard of a 2.2 and the TC2.4 but not a 2.3

1/2 Northstar?

Never heard of the 2.3 or at least refered to it as such

The Quad4 is a 2.3

yeah, I think the 2.3s and the quad fours are one and the same. I've just been working on mustangs for waaay too long

junk motor but some beg to differ
