950 Holley HP on a 496 BBC
I need some help in choosing a carb for my 1969 Chevelle. It is a strip only 496 BBC with 13 to 1 compression, Dart 325 Pro 1 heads, Lunati .722/.722 solid roller cam, and a Victor Jr. intake. The car has a powerglide, 10 inch converter and 4.33 rear gear. I have a Holley 950 HP on it now with a two inch open spacer. I am leary of trying it on the quarter mile because of a lack of cfm. I have access to a 1050 Dominator with a 4150 adapter. Should I even give the 950 a chance or go ahead and switch to the 1050?

950
Since You have the 950 on there, Id try it. I would have the 1050 bolted to the adapter and ready to swap out. Be nice to see the difference. I ran a Dart funnel ram on my 572. Good luck. TC

i run a 496 mine is 10:5 comp. with a little less cam than yours. i have a 950 on mine i run 1/8 its about right on mine. im thinking the 1050 would probably run a little better on your motor. jmo

I have a 750 cfm carb that bench flows almost 1000 cfm. This carb was recommended because I am more street than strip with my 496 engine. Keeping the air velocity up through the carb will make it more drivable vs. a 1050 dominator. I have no personal exp with a 1050 dom but was told that is best for strip only, wide open driving. Won't be very street friendly.
