Re: Project -underfunded - '68 shortstep/carb'd LSx/200-4r build

Harness is being built for me, as I understand it from scratch. I will be running the e38 ecm, truck intake, and dbw. While the e38 doesn't care what trans is behind it and will run with stick or auto...I think I may as well go all the way with this...........meaning a 4L80e at the very least. That said..............I have my mind set on trying to get my hands on a 6L80e or 6L90e. Then later a dana60 or 14bolt 9.5" SF and then I ought to be able to beat on it at the track and still drive it home.

I've noticed some "new" GM transmissions have a core charge while others don't. I guess they are actually rebuilt? Core charges for 4L80's and 6L80/90's are $800-1000!
