What do you have, open to a 5.3, 6.0 or 6.2 pending price. Would like a 4l80E paired with it, but not a deal breaker as I can source somewhere else. Not opposed to something already built either, again pending price. If not built I plan on doing a BTR cam, associated mods for the cam, timing chain/cover heads to machine shop all new gaskets and seals etc. I know some of you guys have to have something stashed away for future plans and can use the dough for X Mas
