Thermoquad vs holley vs q-jets

Yes you redrill. The set screw just makes it tunable. If you go too big, just screw another blank in and start over. Sorry for the confusion, I think it but don’t type it.

Naw that's ok. I wonder if there's enough room to tap that area for a Holley carburetor jet? Or maybe the size of the idle fuel restrictors?
