edelbrock to holley conversion

LOL, I want a Holley because they have better performance than edelbrock. Most everyone tells me that for out of the box drop in and run use the edelbrock. For performance use the Holley. plus it has a really cool dual feed:) I don't have any expierience with Holley carbs but I guess I will now. I'm not scared:) YET!!

The difference in performance would only be something you would notice if you are running the car on a dyno or racing it all the time. For a street or street/strip car it is much much more important to have a carb that gives you good low mid range throttle response than a HP or two more on the top end. You also want a carb that will be without any bad street manners. There is a reason that with very very few exceptions all the performance engines from the muscle car era came with vacuum secondary carbs.

As far as dual feed is concerned that is a poor reason to select a carb. All Holley 4150/4160 series carbs with center hung floats whether they are mechanical secondary (double pumper) or vacuum secondary have dual feed and you can buy a dual feed kit for your Edlebrock carb if that is important to you.

If you already have the 650 go ahead and give it a try but I think you will find that there is little or no seat of the pants difference in perfromance and you will definately have a much more difficult time trying to get it dialed in. Hold onto your Edelbrock, I bet you will eventually go back to it.
