To add to TJ's comment, he is right on about the timing gears. Here's what can happen to the composite cam gear. I bought a '64 Chevy pickup for parts non-running and this is why it didn't run. This engine is a 250. The 230 in my '55 GMC has the aluminum gear. It makes a bit of a whine, but that's better than having the issue this 250 has!
