... Holley 080804 Ultra HP 850s? This is the latest 1.56" venturi x 1.75" butterfly + downleg booster version.


Why would you limit your moter w/that baby carb?



The car ran 10.5s w/ a 1.42" venturi x 1.75" butterfly BG carb, so stepping up to a 1.56" venturi is actually quite a bit bigger...

However, from what few "real world" (NOT a magazine) tests I've seen anything posted about re: this new 850, Holley seems to have missed the mark on its calibration.

I think I'll just keep testing & parts-swapping w/ my "junk" BG carbs that seem to run pretty well after getting dialed in.
