I have the early version in my vert and its the 600 hp unit. Mine has the factory bell that was sent to keisler and machined and uses the stock fork. Mine leaked and shifter like crap at first, sent it back and they upgraded the shifter and fixed the leaks(for a while) now leaking again. Its a great driver trans but will hang up third gear if you try to power shift it.I had no fitment issues though.
I had a 70 road runner with 426 hemi and a standard stock 23 spline 833 that would outshift that keisler any day. I do however like going on a road trip and shoving it into 5th and cruising at 75 to 80
