Since I am looking at shaving weight and getting more serious about track only, my 4L80E is for sale with verter. This is a auto 4 speed with lock up converter. It handled everything my little 347 could throw at it plus a 100hp hit. There are companies that make manaul valve bodies for them like transgo and you would not need an additional electric trans box for the shifting. Lock up can still be achieved with a sitch to the trans harness.

At 65mph with 4.56's and a 30" I sit at 2,450 rpm..

I would not run a 60E.

Let me know if you have interest in it.
