hello everyone,

i am planning out a project for my 98 lumina ltz. im planning on replacing the stock head for a supercharged head. I am unsure about the transmission, because i heard the 4t60-e tranny is rated for up to 280 ft-lbs , and this mod will be pushing that number. should i swap it out for a rebuilt 4t60 hd? or will the stock tranny handle that kinda power?

(the car& powertrain has 36,000 orig miles)

thanks
