I'm currently running a Holley 650 double pumper on my 454 in my 64. It has about 10 years since its last full rebuild. Currently, if I drive it really easy on the highway, i get about 10 mpg. In town lucky to get 5. It's starting to have drivability issues and an occasional leak. I've heard Edelbrock is more reliable and driver friendly with better milege. My question is.... Do I rebuild the Holley again or buy a new Edelbrock? If new, what cfm? Any tweaking as far as metering rods? I'm in Central Cal closer to sea level.
