Check your timing, V-advance hooked to the right port on your carb, that's where I'd start.

what model of fuel pump are you using, a regulator is a good idea but a few of the holley pumps do not require one, but some do!

Bog and backfire is more likely a lean condition, not rich.

It's one of the Holley High Performance mechanical pumps. I don't have the model number handy, but I'll try to find the box for it. I think it's the 90GPH version.
I'm also not very good with carburetor tuning, so I need to make sure I'm running the proper jetting to support this motor. I'll try to find out a little more about it.

It would be nice if this up and down crap would cease.
