My old carburator is getting tired and I'd like to buy a new one. It is for my street driven 72 chevelle. It has a 350 with vortecs and a comp cams 268h cam, edelbrock dual plain intake, headers, 40 series flowmasters, and 3.55 gears. It is just a a street driven car that doesn't see track time but I want a carb that will get me performance with out sacrificing too much gas mileage. Demon, Holley, or edelbrock?

Your combo screams for a Q-jet. :yes: It's hard to beat a well tuned Q-Jet on a mild street small block, especially if you are wanting half-way decent MPG.

If it were me I'd contact Sean at SMI and have him do his "Magic" to one. He will total go through the carb and "tune it" specifically to your vehicle / setup.

I had Sean do Stage 1 mods on a Q-jet for my daily driver 84 C20 Suburban. No problems at all. Drives great! Give him a call, his price is very reasonable.

BTW,Sean also is a team chevelle sponsor and give its memebers 10% off on q-jets and 5% off on holleys.

Sean has done a q-jet for my mild 396 and a 340 mopar thermo quad for me and both carbs ran great out of the box after he did his majic.

I also agree his application would be good with a q-jet setup by Sean that would likely get better fuel mpg then a holley without any noticeable loss of top end power and last much longer befroe requiring and service/rbld work then a holley could ever do and better then most eddy perf series/afb type carbs cold do too.
