Is a Holley 750 DP too much carb?

crackedback said
Had similar builds with a 750dp and got 18+mg on the highway and mid teens around town.

I had no problem getting 16 mpg with a 750 DP Holley on a 360 .030 over and 3.91's with a .484 lift / 284 advertised MP cam.
Gotta keep your foot out of it to do that, though
