Lol stock motor right now, but over the winter, Im doing as much as I can, after this trans my driveline is bullet proof. I ended up doing the driveline first b/c my driveline broke first lol. First the rear, built the rear up, then the trans blew.....
So now I have the TKO 600 going in soon with a 31 spline/auburn/4.10 rear. Good to have stuff that wont break, now I can drop just about anything I want in the engine bay, its a nice feeling.
Im just following the motto of the 5.0, when things break, upgrade.
