2.76 open to 3.55 Sure Grip...expectations too high?

Just keep working the tune of the engine (carb) and distributor. We (and you) will just have to work with what it has. If you start in with changing parts out, then the ball game changes. How thick is your wallet?
Let's just say I wish my waistline was as thin as my wallet... I like the plan to continue tuning it; I think it needs it anyway, and I could use the practice tuning carburetors.

I feel the torque converter is key.
Did it seem to stall higher with the 2.76?
How do I know when it stalls? Torque converters (and stall speed) mystify me, no matter how much I try to read up on them.
