Update fixed the issue! after i verified TDC i found that i needed to adjust the bottom bracket to get my correct initial timing, then she pinged less but still could faintly hear took some timing out of the distributor 14 initial and 16 centrifugal gave me a dead 30 degrees with out V-can runs alot better!

Do your own experiment of running the vacuum advance to manifold and then ported vacuum, and see which one works better for you. When using the manifold vacuum, the timing falls back off as the throttle is opened, but it will still increase torque and low rpm power. You may have to turn the idle sown with it hooked to manifold, but I think you will find increased off idle driveability.

At some point, check to see if you have any vacuum leaks at the intake and consider installing a wideband in the exhaust to help dial in your carb. Also, check and make sure your exhaust butterfly valve is not stuck too.
