i had a pro systems carb built for a 375ci engine and here is the sheet:

950hp main body--822cfm
p/s-pump 50/30
p/s-sqrtr 45/45
pri jet 78 sec jet 86
hi air 36
idle air p76 s73
idle feed 35p
pv feed 55
pv 6.5 plugged sec

it ran pretty rich and i couldn't do anything with it. if you compare it to a bg there is quite a bit of difference. i am using a bg carb on a similiar engine with a few adjustments and it works pretty good, it is an 850 cfm rr carb, probably flows 900+cfm.
