Sorry 904 tranny, don't know about the rear end except it is a 7.25". It's going to be street car for sure, we have no drag tracks here anymore. Gas mileage isn't a concern. Not even slightly skilled enough to know how to figure out compression ratio. Just trying to get something dependable and fun to drive. Still has the old 14" steel wheels on it. Someday, when I win the lotto, I'll do more.
