    Honestly your best bet would be to go to a holley 600 or 650. You would get better gas miliage, and its alot easier to tune. I have never had luck with edelbrock performer carbs, or carter competion series. They both are set up for 500 plus hp motors. Also they use metering rods, not jets like a holley. Every car that has come into my shop with one on it well replace it, weather its new or not. They come in because it runs rich and doesnt idle right. We tell them in order to fix it they need a holley. Problem solved.

    See Tim I told ya, get a Holley.

    Seriously Tim the Holleys are much more tunable.

    You can get new metering rods and all I believe to tune the Edelbrock but Im not sure how expensive they are.

    I know this is not what you wanted to hear.

    Not only do you have to figure out which meter rods to use, you have to find somebody to tune it. I personally dont know anybody that has got one to work correctly. Just look at the dragracing scene, everybody uses holley that has a quick car. I use the holley 750 double pumper with mechanical secondaries on the Firebird. Love it, wouldnt trade it for anything.

    You can buy a kit from Summit that will comes with jets, springs, rods and a manual that shows you how to tune your carb. It's very easy to do.

    I thought the holleys didn't perform as well in off-camber positions? Is this true? If so, it may be fine for flat driven vehicles, but not for our rigs. And some of us can't afford TBI right now. Is this off-camber problem true?

    Yes the off camber prob is for real but not as bad as people like to make it seem. I have never run into a prob w/ it myself and have been running a Holley since 91. Now if I were into rock crawling it may be different. But on hill climbs and bogging I never had a glitch. I am not going near vertical tho. Maybe a 60-70 percent grade. The best alternative to INJ. is a Q-jet. They seem to run upside down! LOL! They make kits to help the Holley in the off camber situations, they also use them in drag cars for fuel slosh under launch.
