Hi Guys,
I don't know if anybody can help me here. I just bought an 81 z28 with a built small chevy 355. I noticed that when I would try driving it, I could here some pinging sounds. So, I checked the timing and the vacum advance is almost touching the intake. I tried to set the timing with a light at 30 degrees @ 3000 rpms and the motor dies. I tried to pull the distributor out and reset it in and same thing. It will only run if it's against the intake. And suggestions on this matter and what should I begin do. Should I tear it down and see where the timing marks are on the chain. Any help would be appriciated. Thanks again....
