Steve,
what power range has Bowler reached on the 4L65's? I had one built for the twin turbo GTO and the builder was comfortable with 1000 hp. It has billet shafts and all the bells and whistles. I was running 15 psi at that point, so not sure it was making 1000 hp, but a friends combo made over 800 rwhp with the same kit, same boost, and a nearly stock LS2.
The trans was flawless, never put up a whimper, and I did run drag radials 100% of the time. Then again, it never dead hooked either. I just wonder if they have a 4L60/65 that could hang in my car. Currently have a 4L80E but have been considering the RR trans and converter, and with your comments on the 4L80's not at the same level has me thinking of moving to the 4L60 series.
