Re: carbarator

I tried a couple of Quads B4. I stripped all the unnecessary crap from them, tuned and massaged, but I couldn't get them to perform like a Holley. I have a Holley 800 Dbl now and it gets as good of mileage as any of at least ten different carbs I've had. But out performs them all.
The Quad didn't do anything the Holley couldn't. For your rig I'd recommend the classic Holley 600, List #1850. Check them out at summitracing.com. Or a 600-750 Dbl if you want the extra performance of a Dbl. They don't get as good of mileage out of the box as a regular vacuum model, but that can be easily fixed.

Good luck

Re: carbarator

Edelbrock performer 600cfm part #1406. I had to replace my old Qjet around christmas. The performer is the cheapest I could find, and the most simple. BE SURE TO USE THE EDELBROCK ADAPTER for your q-jet manifold. I tried the Mr. Gasket brand and had a huge dead spot when accelerating. I got the model with an electric choke but I have installed one with the mechanical choke on a friends truck and both of us are very pleased with them. I havent ever touched my ajustment screws since it came out of the box. I hear the edelbrock Q-jets are good, but from what I have seen not worth the extra $$. I have my base timing set to 11 degrees. I have a 76 model 350 in an 87 swb truck, GM aluminium intake, 4 speed w/o OD, 3.42 rear end gears, and worn out 32x11.50 mud tires. If I run between 50-60MPH on the highway I am getting around 14 MPG or better!! I checked mileage with a little city driving and WOT threw in and got 13.8 MPG on a 50 mile round trip. I have never checked local city driving, but I know its not 14. A PROPERLY WORKING Q-jet would probally do better, but those can be hard to come by. With mileage that good and a noticable power diffrence you cant go wrong with the performer. I took mine appart once to clean it out and that was very simple too. IMHO the only thing better is fuel injection. If my TBI swap works out, Ill post back on the diffrence.

Re: carbarator

If you decide to NOT go with dual 1180cfm dominators (well, if youŽre going to wind your 350 up to 22000 rpms you actually need those[img]/wwwthreads_images/icons/laugh.gif[/img]) IŽd suggest a Edelbrock Q-jet. If you find them a bit on the pricey side (I do), then Edelbrocks Performer 600 could be something for you? I think Shaggy from this board has one of them. He could tell you about the pros and cons if he ever gets his Californian a$$ over here [img]/wwwthreads_images/icons/laugh.gif[/img]
