    Bolt it on and crank the boost up.

    Nelson Performance front mount 76/96 on a mostly stock engine with about 10-12lbs should net you well over that. My cammed 5.3 with 12lbs makes 554/557

    Stall depends on your can but usually a 3200 if your boost comes in low. I've been thru 6 trans with my set up, one 4l60 four 4l80's and a 700r4 that I slipped the clutches in Wednesday. Got a th400 in the works. If I had it to do over I would have built the trans before I built the turbo kit.

    Sounds like u have a tuning problem not trans, or driving wrong...

    I would say, valve springs, pushrods, tune (nelson does the tuning) and then a strong trans for anything 5-7lbs or more. The stock trans wont last long at all. I had a fully built one when I had my first turbo, so I didn't worry about blowing the trans at all.
