Hey guys, what do you think works better: an Edelbrock Performer or Performer RPM spread-bore intake manifold with a spread-bore carb like a Thermoquad, or an Edelbrock Air Gap square-bore manifold with a Quadrajet or the equivalent carb?
Why do you think the Air Gap manifold is manufactured only in the spread-bore configuration?
I've always wondered about this, so figured I'd ask. As always, thanks a lot.
Do you mean square bore? I've only seen the Air Gaps with square bore. If that's what you mean, my guess is they figure most people have a square bore aftermarket carb for this intake instead of trying to use a Thermoquad with it.
