2.8 MPFI to 305 TPI?
Hey guys, I was wondering the difficulty of changing my 2.8 (On it's way out) with a 305 TPI. I get decent gas mileage with my 2.8, but really not enough to warrant keeping it, it's got cracked manifolds and stuff, and I don't want to put another 6 in... So what would I have to change in order to get in a 305 TPI?
