930 cfm carb questions

[elcoman]

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?
