1977 Pontiac Ventura stalls out

I just recently purchased a car that I think has a lot of potential, it's a 1977 Pontiac Ventura and it was stuffed with a Chevy BBC 454 fitted with an older gm 671 generator blower and 2 4bbl Holley carbs,
My question is what are the possible reasons that the car would stall out under load but does not sitting at idle.
Thanks in advance

Welcome to Hotrodders.

I moved your tech question to a proper forum. I altered the thread title since "Need Help Please" type titles do not function well for the membership.

I deleted your other post on the same subject.

You'll have to clarify what you mean by "stalls out".
Do you mean it actually quits running, and you have to restart it?? If so, does it start right up, or need to be cranked a bit??
What RPM is this occurring at??

Mechanical or electric fuel pump??
Fuel line size from tank to pump??
Stock fuel tank and stock fuel pick-up in tank??

Originally a V-8 car, or a straight 6 car??

A more detailed description of the whole engine. carb, and ignition set-up may show clear up the picture for us.
