I may agree that he doesn't need a built tranny now but at 20 plus lbs of boost he will need one soon , just sayingAt 24 psi spraying alky, it should burn the tires most of the way through 2nd gear. If it doesn't, somethings wrong.
All this talk of convertors and bigger turbos etc., flirts with "now it's a race car not a street car".
I ran pretty much exactly what you have for 5 years and never hurt anything.
TA49, 60's , alky, STOCK convertor. It's about the tune, 11.8 @ 115 all day on drag radials.
I disagree , you don't need a built trans, convertor for your power level.
