BG825 with a 1.75" butterfly and 1.425" venturii
Holley 950 with a 1.75" butterfly with a 1.375" venturii
Or have a 950 holley main body cnc machined to 1.425"-1.450", Pro Systems could help you out with that

of the two you listed ,i would go for the 1000ho . OR an equivalent out of the box holley hp1000 . Looks like you should knock off 2 seconds from your previous best .

I have a similar combo but with a little smaller lift cam and ordered a prosystems carb. They recommended a 1000 cfm 4150 for my application. I hope that helps, give Patrick a call.
