Anyone have anything good to say about a Demon carb? I went from a worn out Holley 650 DP to a 750 Demon w/mech secondaries but the 5 mpg was to much! Swapped it for a 650 Demon with mech sec. Mpg up to 10 -11 mostly highway which I can live with. Neither was an out of the box job. Both needed alot of work. Low end drivability is not much. Going thru the gears & top end is great. Won't idle til completely warm and a PITA at all stops. Got to keep the revs up to take off. Feels like a close box & no rear gears. Well it's a 252 first & a 3.73 rear. Cam is a Comp 274 Hi Energy Xtreme, 236 dur 490 lift. Down from a 284 in the six yrs I've owned it. The guy at BG says too much cam & go to a 575. Wouldn't that kill the performance!!! I've got a TKO 600 with a 2.87 first going in this winter which may solve it all and give me both low end drivability & 1/4 mile performance. Why don't I go with an Edelbrock which most people say are great right out the box? Probably the Look. Some of us just prefer the Holley/Demon look. All thoughts, comments, ideas, advice, or just ventilation appreciated.
For anyone that was at the MCC/ACES show at North East, MD Sat and/or Sun, wasn't that "Some Show"? Over 200 Chevelles, great weather and great people. That loaded 383 stroker that was given away kept most everyone til the end! I applaud the MCC leadership and all my hard working fellow and fellowette members for another terrific show and a Great weekend!!!

If you go holley make it a double pumper. Quadrajets and Edelbrocks will work well too.
