Long story but I'll try to keep it short. I bought a 66 tempest custom was supposed to run just needed a new coil, ended up needing a timing set. Ran fine after that for a bit then ate a cam lobe. I contacted melling they suggested a larger than factory cam, had to go to poly locks to get the valve lash correct. But it still runs poor. Its got new plugs, wires, coil, distributor. Rebuilt carb. Is the cam they suggested to big?
