Very nice '57 ......... has the right look and the perfect stance
That sounds like a good plan. It should sound good and have plenty of grunt. Car Craft did a build of a motor like this and it made about 420/420. You'll probably have more power with the single carb, but the dual quads have the look!
The combo that you picked is almost exactly what I built except I put on aluminum Vortec heads and an air gap intake with a 750 e-brock. I am in the process of putting it on the break-in stand and will post a video.
Are you going to have to cut a hole in the hood?
Icody I think I would just put a gasket kit in the holley, a lot less than buying a new eldebrock sense your changing intakes anyways...
