W2 Stroker comin together!

For sure, a sound plan. Interestingly, late last summer I swapped in a 2.94 center section for a long road trip. I left on the 950 to see how ugly it would be with those gears, then swapped to my Quick Fuel Q750 thinking the smaller venturi would help with the lower engine speeds. I can honestly say I noticed no real difference in driveability with the 950 vs the 750 which surprised me. On the street any extra power with the 950 is lost in tire smoke anyway, I will test at track this coming season.
Unless that carb was a recent ultra xp model the 950 is not really a 950. The new one are now being marketed as a true 950. 1.750
Venturi size. That could be why there was no difference.
