I've got a 482 with an 850 Quick Fuel. Mine is the Q series with AN boosters. The weather right now is in single digits, and all my info is in the garage. I know when I had it on the dyno doing A/F we had to pull jets out of both ends, then fine tuned the fuel curve with air bleed adjustment. I'm pretty sure the drag race 850 came with bigger jets than you have listed... I'm thinking 92 and 84....and we ended up pulling 5 or 6 out.

Thanks for your response. You may be right as I looked it up at Summit and looking at Quickfuel's site it looks like the primaries were 78 and secondaries 84s. I do have the RQ850 Drag Carb. If it warms up in the next couple weeks and you get in the garage appreciate knowing your setup. Thanks.........
