gm t56......
 

just bought a 96 formula... was thinking my speedo was off cause i was doing 1600 rpms at 70mph... i checked 4th with 3.42 at 65 is right at 3k.. so speedo isnt off.. but my question is... is this thing a ZF-6?? according to the gear simulator.. my 6th is .50 :/ maybe the guy switched it out... whats a stock t56 with 3.42s rpm at 70? just trying to figure whats up :) thanks
