Hesitation is gone after cleaning the Edelbrock carb...and when using the Holley carb.

Yes, what I meant to say is, I'm checking the initial and total with the vacuum advance disconnected. 16 initial, and 30 total mech in.

I'm not sure what RPM the total mechanical is in since I'm under the hood.

I do use the vacuum advance when driving... and I connect it to ported.

So now my main problem is, lack of power at mid-to higher RPM.

Although torque at launch isn't that impressive either. I had a 318 2bbl that felt much stronger than this 440.
