I sheared a dizzy pin in. 302 once. A piece of the nylon from the timing gear got into the oil pump and locked it up. The pin gave enough resistance to move the dizzy somewhat when the crank moved, but it was pretty apparent what the problem was.

Well it all came clear today about the timing problems the 302 small block was having... after having it tested once again by a very smart guy here in town it came down to a bad coil..... not sure what went wrong with the coil but it appears that it was breaking down... The shop that did all the test and thought it was a timing chain that had skipped was wrong and they refunded all the money he spent with them to test it... Pretty nice of them it think...... something to think about next time the old motor starts running ruff... COIL...
Thanks for posting back what fixed it. That's one of those that reinforces the need to eliminate all of the simple stuff before jumping to the more complex. Funny that it "ran fine" with the timing so far advanced, but glad it's fixed for the guy. Getting the refund from the first shop is definitely a bonus, and not the norm in my experience.
Was the coil OEM or aftermarket and if aftermarket whose brand?
