Quick Fuel vs. Demon

smeadphotoMember

I’m looking to replace the mammoth 850 Mighty Demon with something a bit more streetable, and altitude-change-friendly. I’ve read through Sticky #3, and searched the forum for carb advice, and have narrowed my choices down to either a Quick Fuel SS-750-AN (750 cfm/mechanical secondary/electric choke) or a Speed Demon 1402020 (750 cfm/mechanical secondary/optional choke).

I’m running quench heads, with an Edelbrock Performer 4V intake (#2665) and the cam is a Hall HP-2, which I think is a Crower.

The goal is better low-end, and mid-range response (right now, it chugs until about 2500 rpm, then it takes off like a bat outta hell), and fewer dinosaurs exiting then tailpipes at altitude (I run from sea level to the Haleakala Summit – 10K feet – on a regular basis).

Yeah, I know the optimum setup is EFI, but I just bought the wife her dream car for her 50th, and had to divert some “Pantera Funds” to make that happen. I’m stuck with a carb for now.
