What OD auto behind a built Twin turbo 383 LT1
Like stated in title whats a good OD for this should be pushing 500+ the car is a 95 Impala SS. My buddy just built this setup for his client but his 4l60 can't handle the power it kicks outta gear on hard acceleration. I was thinking just going to 4l80 and building it, but can he build up the 4l60 to last??
