Both the rich mix and the fuel pump can cause the problem. Of course the electric pump eliminates this in your car. Also, if the choke stays on too long, or if the car is started several times and not allowed to fully warm up before shut down.
Be sure to check the PCV system. It vents the crankcase. If the PCV does not work, nothing vents the crankcase and the fumes build up.
In any event you want to cure this before you dilute the oil and cause engine damage.

Scott,
Are you using F.I. with the blower or a carb?
This happened to me, it was due to a leaky carb that bled out after every start. I had it rebuilt & the wells capped with epoxy.

When you mention capping the wells, please explain.

The wells in question are in the qudra jet carb. You don't need to worry about them in the holly. Just the kit and new floats.

I think the holleys were bleeding gas down and fouling out the plugs.
I actually might even step down to a leaner setup.
