I spent the last couple weeks working hard on finishing my LT1 383 4l60e install. I have ran the engine several times with NO starter noise or starting issues, bet I started it at least 50 times. This past Sunday I finished up the shift linkage, exhaust and a few other minior things. I even took it out for a quick test ride around the block. Ran great, no problems, started a couple more times and then parked in shop. Everything was looking good, so I thought.
Went out this morning before work, reached in, turnded the key and..........I can't even type the words of the sound it made. After the noise stoped, the started just spun. I ended up pulling the access cover of to inspect the flexplate and starter. The flexplate has about eight inches of teeth missing (found them in the cover). WTF I can turn the engine over by hand past the broken teeth and it starts right up.
Has anyone ever seen this before or any suggestion on what might have happend. I need to replace the flexplate but want to make a habit out of it.
