600 CFM vs 750 CFM...

I'm currently testing a 600 holley double pumper in place of a 750 holley street hp. It idles better, had better throttle response, get better mpg, and has a choke.

Definitely lost a lot of seat of the pants power but all around drivability is way better.
I'm on the hunt for a cheap 700 (0-4778c) or 750 (0-4779c) holley to test out.
