Need help NON mopar 1967 Pontiac Lemans 326

Did u just put the cam in also? Negative. Haven't touched the bottom end.

It could be sucking air from under the intake ports. stick a rubber hose over the end of a propane torch to get between the intake and the valley pan?

Is a spring off the weights under the rotor. I'll check it out.

not actual engine. just pics to show intake
