3.09 gear set with 3.23's
So that leads to the final question; What's wrong with either; your combo, your stall, or your TC itself.
Whoa! 200psi@1200' ; so those ain't the problem,lol
That sorta leaves just the convertor.

I gotta say that I love my 3.09/3.55s/ at 177 to 180psi. When I installed the Hughes HE3037AL That 367 of mine lost a bunch of take-off torque, compared to the HE2430AL. The only way to get it back was with 4.30s or the 3.09 low. I ran the 2.66/4.30 for one summer, for a starter gear of 11.44 just to prove I was gonna like it, then pulled the trigger on the 3.09 x3.55=10.97. Which has been in there ever since.
Second maths to hit 60@5140 perhaps a lil low. But using the GV as a splitter, she maths to 60 @ 6450, on the way to 7000@65mph..... with only the one full-power electric-shift. So basically, when I stomp it, she goes to the rev-limiter and stays there to 65 mph. So for me, the 3.55s are the right gear.
Peak torque comes in the speed-range of about 40 to 50mph in second, and the lil 367/750DP breaks the 295s loose with just a footstomp, and they sometimes keep spinning into third gear at over 80. It's a good thing those BFGs are quiet.
