Yet, its being done for very powerful hot rods all the time. I think I even had a 700R4 in one of my Corvettes. The 700R4 monster upgrade kit looks great but at a very expensive price. I bet you know exactly what and how it needs to be done

Well it's been 9-maybe 10 years since I've been active on this forum.
@ my age I'm lucky to remember what I've had for breakfast!
But I will try.
The 700R4 works well and will hold up if you don't pull a heavy trailer with full throttle starts.
I put in a beast sunshell, kevlar band & clutches, 'Vette servo.
use an '88 89 trans if you can as the earlier ones had a few drawbacks.
put on a deep pan and use a cooler.
As far as holding up ya they are ok.
The best was the 4L80E as they were basically a turbo 400 with overdrive.
I do like the 700R4's low gear, as it will give you a good hole shot with a #10,000 load.
yer not gonna get 20 MPG you will pick up 3-6 average, with no headwind.
You will have to slide the rear cross member back a few inches IIRR.
and I engaged the torque converter lock up with a vacuum/electric switch, and shorten the driveshaft a bit, but it has been too long to remember.
I still like the good old days when we had simple carburetors and no friggin computer controls, but life & rules roll on.
