I bet if you get rid of that gas guzzler Holly and the Rpm go with a 600 Edelbrock and a Edelbrock Preformer the miliage would come up and you would not miss that much preformance.

Probably true, but I like the set up.
I have a positrac lined up with a little higher gear ratio that should help quite a bit and not lose any performance. That'll be my next mod.
