Doubt you'll find anyone that has flow tested a carb, but it sure does stand to reason that there will be some, if not 200 cfm more
68 Hemi GTS!
Thats good news. I had a Proform 850DP on for a couple of season before I try my old Holley 850DP (4781) which outperformed the Proform 850DP on the track.
I just put on a 1050AN main body on the 850 proform carb, I hope it be a good street and strip carb. I have only take a spin around town for now.

I can post my calibration if your interested. Car ram 10.90’s in street trim with that carb.
You could measure it to be sure, but I’m pretty sure a PF “850” Race carb(no choke) has a 1.450” Venturi........ so the Holley’s 1.562” in the 4781 is noticeably bigger.
I believe the 1050 annular has a 1.590” Venturi........ but the boosters are more restrictive.
Thanks! I would appreciate that. It should save me some time and gas

Had som time to look a little deeper and CLOSER in this carb now.... And what I think was my .028 jets in the EMU was a plugg and NO jets in the other holes I guess Im getting old and don't pay attention anymore
This is now corrected .028 plug .028 plug. I enlarged the pvcr from .055 to .063 and it was in right direction..... but not enough. Gona drill a new set to .071 and test.
Now the question! Do I need High Flow P/v now to meet the enlarged pvcr?
Thanks!
