Respect you and crackedback a lot. I appreciate your inputs and help! But man you guys are on the opposite sides here, aren’t you? Lol would love to see you guys go at this directly lol and have me sit back and eat popcorn and learn what I can from the discourse.

I think we both agree that on a street car you need VA. Whether that is ported or manifold vacuum could be deter by how the engine is built.

At 12:1 on pump gas, I’m going to try and get VA to work off ported vacuum. I don’t see a scenario where I would need manifold vacuum at idle.

I’m also using an electric fuel pump with a return like and the regulator is boost/vacuum referenced.

Hooking manifold vacuum to the regulator will drop fuel pressure as manifold vacuum increases.

This will lean out the carb at a cruise.

I’m thinking between VA and the vacuum referenced regulator I’m hoping to get my cruise A/R about perfect.

Of course, I could be bat crap crazy and wasting my time.
