Quoting Removed, click Modern View to see

I sprayed some carb cleaner around base of carb and manifold and no change in engine sound/rpm. Seems there is no vacuum leak.

Checked fuel pressure and it was steady at 6 so I'm good there.

Took the car for a rip and it was pinging. Not sure how the timing changed but it did. Backed it down to 14. Got dark. Will run it on Saturday to see if that's helped.

To answer your questions....

10 months old Holley 670 Street Avenger with electric choke. 4 speed toploader. Idles fine but a bit sluggish on take off. This car just stinks of smells all around but I can't say any worse than usual. It is an MSD distributor WITHOUT vacuum advance. From what I've been reading I agree that my total advance should come in at least 800 rpms sooner.
