Dude r u kiddin' .... that's a killer setup and I remember you recently got the exhausts done and boosted HP at the wheels ....
The best performance is obtained with a converter that has a stall speed slightly higher than the rpm of the engine when it starts to produce its strongest usable power. Too low of a stall speed will result in a bog, and launches will be slow, since the engine will not be in it's usable power range. Too high of a stall speed will result in the engine reaching its peak power range below the rpm.
You don't say what the type or range of your converter is so it's hard to say but .. for your diff ratio and since you say she rips at 2,200, set it to 2,400 - 2,800.
It is very important to match all of the engine components; cam, carburetor, torque converter, rear end gear ratio, etc, to work in the same rpm range for the best results.
So .... my personall recomendation, stick 3.55 in the butt and set the TC for 3000.
You may also want to consider a Holley double pumper (750 or 850). Not sure but I think your QJet will be primaries / secondaries setup so the Holley will get more juice into the belly.
At the end of the day, it comes down to your bucks for bang ratio (how much you are prepared to spend and what your expected output is).
That's my opinion, if you want experts, call Steve from SR Performance and see what he tells you ... even though you're unlikely to be his customer as you're in another state, he's a good bloke and won't mind giving you advice.
This is a great question and posting 77cvt, we need more of this techo stuff ...
thnx ....
