    I have my gas tank removed right now while I'm installing a shackle flip kit.

    Is it worth it to install a high volume fuel pump while the tank is out right now?
    Is there a performace gain with a high vol pump?
    What should I expect to pay for one, and where can I find it locally?

    Thanks,

    Thomas

    Just an opinion here, but there is no reason to run a high pressure or volume mechanical pump on a Quadrajet, if that is what you are running. The carb design itself will be the limiting factor if you are running out of fuel at high RPM's, since the fuel pump works in relation to the camshaft..the faster the motor spins, the faster the fuel pump works. I don't think I've really ever heard anyone complain about a stock fuel pump. I believe my friend thats a circle track racer (continous 7000RPM small block Chev) is running a stock mechanical fuel pump.

    I wouldn't bother. I think you would notice 0% difference. Your stock mech fuel pump puts out plenty.
    I just put on a new mech fuel pump on my 350 - it was like $11 from Autozone, no core. Just put on a new one so you know its 'not worn out and forget about it for another 10 years.
