Holley idling issues

Sounds like a sick *** ride! As in bad ***! Seriously, almost every one I've ever built does that when good and hot.

It is a beast, I have to run street slicks as street tires won't hook up.

hot and higher fuel pressure? Does it have a functional bowl vent?

Fuel pressure is consistent, I haven't checked the bowl vent.

What type of carb spacer are you using?

None, carb is bolted directly to the manifold.
