    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.

    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.

    Stock transmissions lol but my built 80e rolled the overrun sprang on the downshift. Tired of fooling with the 80's the th400 is much more budget friendly to build
