Transmission Upgrade
I'm about to upgrade to an A&A supercharger for my former H/C/I build 2001. LS2 will be bored out to close to LS3 displacement, forged bottom end and I will probably run a 3.4 pulley. Running 3.73 rear gear and anticipate a stall speed of 2800-3000. I expect to be at 650 horsepower to the wheels, if not more.
Question: Which level of 4L60e from RPM is suited for spirited street use and RARE drag strip days. Mostly just some WOT launches on highway on-ramps.
Currently have a lvl 4 and was debating between a lvl 6 or 7.

Get the strongest your budget will allow. One less part to worry about.
Do you plan on replacing that UD pulley with a stock diameter or larger one during the blower install?

The UD pulley was going regardless... I hated every minute of it. Probably back to stock diameter as I'm unsure of the benefit to a 10% OD vs overclocking my accessories.
