Re: camshaft help
Are you saying that your car has a mechanical fuel pump?
These cars typically have an electric fuel pump.

Re: camshaft help
if its mechanical, you have to remove the fuel pump to pull the old cam, im pretty sure all the edelbrock cams have fuel pump lobes. are you sure you put the fuel pump pushrod back in?

Re: camshaft help
did you check to see the fuel cam lobe is under load when you installed the cam?
there is a spring actuator in the mechanical fuel pump. you may have wrong length actuactor for the cam.
if you disconnect the fuel line to your carb and crank the
motor does gas pump out?
