Are you sure the 39lb injectors are up to the task? IIRC a stock GT500 with an M122 uses 47lb injectors.
I went with a set of Deka 60's on my swap.
If you get a chance post up a pic with the COT installed
Yes, I'm 100% sure. I speak from experience. I blew my stock trans soon after installing my Trilogy SC (13.5psi) and I was no where near 700TQ. I now make about 640HP on a built 4R70E transmission with hardened everything. I'll see how long this one lasts.
Terry is the creator of the eaton swap brackets. I've had a set, they're the real deal.
Jerry is the new best thing for brackets. I currently run his HD brackets and a TVS from a GT500
And yep!! budget for a trans.
Join MM.net its a lot of info over there on doing the swap.
