i just picked up an 830Hp 4150 for cheap, then started doing some reading, it has the 1.56" venturi.

i would maybe look for a holley 950DP, as the venturi is smaller than the 830 and 850 holley carbs, might work better.
maybe consider picking up a clean used one (any of the above ^) and send it to Thumprdart to get adjusted...
