To be totally honest I'm more and more just considering selling off the old power train stuff and building either a modern swap ie gen 3 hemi or just getting a newer ride that's already fast. I'm tired of just spinning wrenches and spending way too much money.
I almost bought a C5 Vette when shopping for my Valiant, for it general all around street performance/handling, it would take a lot for my Valiant to be on par especially after few mods to the Vette.
