Quote: A 950HP is smaller than an 850 DP. The 1000HP is basically the same carb as a 850 DP. So I'd say that you wouldn't see much difference at all between those carbs unless one of them wasn't set up correctly.
The 950HP is probably the best carb to run on the street but it might slow you down just a tad at the drags. Typically the 950HP will run better than a 850 DP on the street unless you have more than 500 ci.
ANDY can you tell us how the 950 is differed than the 850 it flows less
Quoted from Captain Budget:
"
A Holley "950 HP" is basically a streamlined 750-size (1.38" venturi) main body w/ an 850 (1.75") baseplate. IIRC, that's worth 820-840 cfm from what those who have flow-tested them have said.
A Holley "1000 HP" is a streamlined 850-size (1.56" venturi) main body w/ a 1.75" baseplate. I don't remember what those supposedly flow, but I'm pretty sure it's well below 1000 cfm. "
When I purchased my 1050 QF Annular Booster 4150 they claimed it would flow every bit of 1050 cfm. I think the QF/Pro-form main body is a different animal from the Holley.
