Maximum HP in 904 Transmission With the following parts:

Just got off the phone with Andrew Racing, nice guys, we chit chatted about my stock rebuild 904 with a TA RMVB as to how much HP it'll hold, told him i was alittle concerned about spraying it with 100 shot, he said a stock 904 willl hold up to 600hp, Yep i said 600hp, they do it all the time, the only weak area at this point is in the spline shearing off, so he said 400-450hp NO problem, i'm good to go.
