930 cfm carb questions
 

Barry Grant DP 930 cfm questions.

I have an older Barry Grant 930 cfm carb, it is a reworked Holley 4779. A tech from BG said "The original jetting would have been 74 primary and 84 secondary with jet extensions on the rear. The pump cam would be pink. The old stage 3 carbs flowed a little over 900 cfm in the 4779 version."

I have 78 primary, 88 secondary, with a pink cam on the secondary accelerator pump, and white cam on the primary side. Rear PV is blocked.
Engine specs:
463 BBC
Solid cam 236@50 .561 lift
Merlin heads oval port milled for flat surface
comp about 8.6
Edelbrock Performer RPM airgap
1 3/4 full length headers
3 inch exhaust
T-350 2500 stall



Is there anything I should change on the carb?

How dose it run? What are you trying to accomplish here ? seems really stock.

I want to use this carb for the 1/8th mile track near me. I want to be able to drive the 40 miles to the track, then run it.
It runs awesome with the 750 VS Holley on it right now.

It seems like you would have to know how it acted in the condition it is now, in order to determine where it may need adjustment.

Well here is a more specific question. Is the pump shot suppose to be equal for front and rear, or does one get more, while the other one gets less? I want to heading in the right direction when I put it on the car.
