Not ambitious enough to scan all the graphs now and should really start another thread but because 4150s were mentioned here's some info we found fwiw.
The 4150 on a Vic Jr
674hp @ 5600 with an average 514.
645lb @ 5300 with an average 610.
The 4500 on a Vic Jr
686hp @ 5800 with an average 529
659lb @ 5300 with an average 620

Nice. More average torque with the dominator as well.

Yes outperformed it across the board and this particular 4500 was the first generation when they called them NASCAR carbs. I imagine a modern one would have done better. All the later 4500 testing was done with a modern QF

SB- We also tested a 454 R / 4500 with no spacer, 1in spacer and 2in spacer. We hit the hp peaks with all the combos, didn't cut any short. I'll start another thread when I can with all the info. Still not done yet. The 4150 in the above test climbed so well to 5600(the limit of that pull) that everyone thought it would keep going, but when we did another pull to a higher rpm it was all done at that original 5600 peak. I don't know what to tell you about the peak to peak spread.

Did the 4150 go 'fat' by any chance at/after 5600 and fine before it ?
