There aren't many BBC fans here. Remember you'll make more hp with a plug wire off, than most with a perfect tune, lol.

I took the air filter off and try to crank it but I don't think it's getting gas. However if I pore a small amount of gas directly into the carburetor it cranks right up and runs fine.
I cleaned the fuel filter (it was a mess) cleaned the distributed cap & sprayed carburetor cleaner in both carbs.
Unfortunately the car does not have a fuel pressure gauge. This car sat for about 2 years before I purchased it.
Any advice? Is this a bad fuel pump?? Spark plugs?? Perhaps this car was not built for street gas??
Would love some help.

What uxojerry is referring to is the port volume of the heads.... .
If that car has been sitting for a couple of years and is running rubber braided fuel hose, the rubber could be coming apart inside the hose and clogging things up.
Another thing I've seen when a car sits for a long while is the fuel pump diaphram gets weak as do accelerator pumps in the carbs and does not pump enough fuel when trying to start it via cranking it over...IMOHO get rid of the 2 carbs and get a single Holley or electronic EFI unit. BTW very nice car
