Cannot decide on trans, been a while

[Thanos]

Last time I posted was a ways back its been a long trip and still working on the 72 along with many other projects.


So I have a 04+ 8.1 (without egr) going with Howell engine dev for comp.

My 72 has been converted to a 1 ton dually for towing/toy not a DD, I have a nv4500 in the mint or can go the route of a 4L80e. Truck has a th400 in it currently so I am looking for input on best transmission for tow/toy between the 2.

I don't think I will leave stock however 500ish+ torque is good enough for me off idle. I have read Dirtylarrys post and he seems to be a wizard at these 8.1L so I hope he chimes in. Money is not problem between the 2 transmissions and what ever one I run with will have a gear vendors.
