i recently decided to make some upgrades to my 350 out of my 69 camaro. i replaced the intake with an edelbrock airgap intake, i put on some ceramic hooker headers going out to american thunder flows...and put in an alluminum radiator. i also converted the fuel line to a non-hard line (rubber hose). i am still runnin the engine with the 650 quadrajet which is pretty dirty and probably hasnt been rebuilt in a while, and i ama also stillr unning a mechanical fuel pump. the timing seems to be ok but i cant get the car to stay at idle...i have to rev the engine to keep it running. i was wondering if you thought this was a fuel pump/carb problem, or something else. anybody have any ideas? please let me know
