Auto tranny is pretty solid...Im pretty sure your good up to somewhere between 300-400whp

however its a good idea to stop boosting around 7PSI or 300whp before you build the engine

Yeah Minesbetter was pushing 13 psi on his auto and it held up fine. I would talk to TC about getting a built tranny if your concerned. You should worryabout getting a shortblock first though if you have big plans.

Also do you need the fuel pump with the 2.75 pulley? I thought you could get away with just injectors

I have the 2.75" and 6.5" pulleys with no engine or tranny probs.

The autos are strong. You'll be fine. Unless of course your tibby03 and trying to break the sound barrier (haha Lou).
