i was just wondering what would go if i was to run 500 hp on a stock trans i have heard the input shaft but what would hold 500 hp i was thinking billet input upgraded torque converter and valve boby send me what you think

 

input will be very iffy... will totally depend on how you drive. other than that a good TC and VB and you are good to go.

 

for 500hp id do a complete rebuild ,vb ,tc , and input shaft and id also throw in a good billet flexplate

 

if your going to do boosted launches add a billet output or you will not be happy. but yes a good triple disc converter, vb and input output will hold fine
