Irs and transaxle swap into 1970 Chevelle
So I'm planning out a build and I'm trying to figure out how I could use a 4l80 instead of a 4l65/4l70 because I don't trust a 4l70 behind a 540 big block, whether it's naturally aspirated or twin turbo'd idk yet, probably going to be twin turbo'd. I know that I'm going to need a custom length torque tube, a different driveshaft, some method of coupling the driveshaft to the torque converter, but beyond that, what else will I need to figure out?
Anyway, thanks for any info.
