Symptoms of wrong cam installation

IMO the 950 carb/single plane has very poor booster signal down low. My 340 runs better with a smaller venturi.

i ran a 950 on my 360 with low compression and that same cam. Ran excellent.
Generally a 950 is same venturi as a 750.
I ran a 950 on my 318 too. It loved it a tenth better than it did a 750
