1985 GSL Fuel Pump/Carb question

hey Gang,

I'm gonna be getting an 85 GSL hopefully this weekend. I had a few questions I wanted to run by you guys so I know what to expect.

The owner of the vehicle put in a racing beat intake and exhaust system. On top of the intake he has a holley 660 cfm carb off a 1980 1 ton Ford Truck. He says that after a while of driving it acts as if it runs out of gas and has to pull over and wait about 2 minutes. This to me sounds like it just needs a more robust fuel pump to keep up with a carb that size. Does anyone know the GPH rating on the stock GSL fuel pump? Is there a good place to go online to order a new fuel pump to deal with the carb output?

Also, does anyone know of any Good places I can go to get equipment to make my own carbon fibre/fiber glass body parts?

i don't know the rating on the stock fuel pump, but i know it's not enough for a phatty carb. especially if it's old and tired.

Definately need a better pump, and a regulator. Ill tell you this, that carb is too big for a 12A, but if its a vacuum secondary carb it wont be too much of a problem.
