ok got some new stuff in and a few things I havn't listed yet

LX5 Throttle Body (not sure if it will work yet but pretty sure it will)

New Motor and Transmission mounts. Inserts are made for the isuzu transmission but another member contacted the company and they claimed they only needed to be frozen then shaved down to fit in the getrag and looking at them they are really close.

looks good. my dad had a 1990 grand am gt h/o with a 5 speed and a quad 4. very quick little cars. my dad pulled on 5.0 stangs with his.

They are peppy little cars stock indeed 5.0s are overrated these engines were pulling more HP then almost all V6s of their day and some V8s that was why the car magazines were all over them but a few bad things gave them a very bad reputation that eventually killed them even after GM had remedied the problems

My son, Coolmanvette beat me to the story!!! The Quad4 is one bitchen motor but the early ones, 1989 and 1990, used to eat head gaskets. I'll never forget the look on the mustang drivers face after I pulled him and he caught up to me at the next red light.

Good luck with your build :welcomeFP:

Ok well smaller update but something is finally done! Picked up my transmission today which is a 93 SCX transmission that I had the 5th gear replaced on because it was all chewed up and all new seals and bearings installed along with a Team Green LSD insert. Overall I'm very happy with the outcome.

Rods finally came in yesterday just waiting on the pistons and valves to come back from the coaters. Getting really close to being able to assemble and balance.
