Ok so I'm somewhat new here and I've got a question about my tranny. The truck has 148,xxx miles on it and the tranny is starting to go. I had planned on swapping out the old 4L60 for a 4L80 with future plans of dropping a 408 in and shooting for sub-12's. Not sure of power adders yet...I'd like to keep it N/A, but you never know. My question is would it be better to go ahead and do the 80 swap or just rebuild the 60? Maybe a 65? Any help and advice is greatly appreciated.

yes do 80e
1951 3100
1984 C10
depends on your funds, read up on what is required to do the 80e swap.. 80e is much stronger
Who cares what it costs, it'll save him money in the long run.
GET OUT OF HERE WITH THAT RICER MATH!

cross member just add a plate with some gussets to it for the mount youll need a vss plug and enough wire to wire to run it from the pcm to the tranny, and shortening the driveshaft
