The Quick Fuel 750 VS carb is getting lots of play and folks seem to be happy with them. I think the Quick Fuel guys used to work at Holley, but don't quote me on that.

Anything from 750 to 850 should be OK for a mild BBC, depends on how mild as to which one you go with.

My personal choice would be an old 3310 or 3310-1. These both have 2 metering blocks and are 780 cfm. The new 3310 carbs (3310-2, 3310-3, etc,) are rated at 750.

Wow, we must be on the same page, LOL. I just removed my 870 Holley SA from my BBC and was thinking about replacing it with the 82750. The 870 ran very good, however I couldn't dial in the choke for some reason and it never really worked properly. If I had to do it again I would not recommend the 870. I think it was a little big for my set-up. Perhaps the 770. Anyway, JMHO. Right now my choices are between the 82750 and the Quick fuel HR780 vs. Here is a link to the QF carb: http://www.ebay.com/itm/QUICK-FUEL-...pt=Motors_Car_Truck_Parts_Accessories&vxp=mtr
