I'd do a buitl 4l60E

I think you need a new crossmember for the 80.....plus its heavier....


yes its stronger, but in my opnion, not worth it

Depends if it's a 9-10 second track car or an 11-12 second daily driver/weekend street car.

Not in a 9 second car. I know quiete a few guys that'll kill any 4L60 inside of one season.

The TH700R4/4L60E is good up to about 700hp, even behind a big block or supercharger.

The 4l80E is a TH400 plus an overdrive gear and is just as strong as a 400... These were found on some trucks and never came stock in any f body or Corvette. You can swap one in, but it needs a new crossmember and driveshaft.

Doesn't the 4L80E require all new electronics

Body mounted torque arm as well.
