and there it is…… again. I have two 904s. One is a stock component build with attention to detail. Only “jewelry” inside it is a Pro Trans Brake, A500 pump gear, and an A&A front clutch spring pack. All drums have oil relief hole drilled in them to relieve centrifugal weight. It was built to go behind our 400ish iron head 360. On a whim I put it behind our mid 700hp W8 mill. Now I know 3 guys personally that have snapped shafts, two at lesser power than me. Well the lil trans that could survived over 100 trans brake launches with 1.24-1.30 60 times. It worked flawlessly and still looked good inside at 80 passes. We carried parts to repair it onsite, but never had to utilize them…… and who really wants to pull a trans at the track and tear it down to the nuts anyways.
