Not what I wanted to hear :-(

I think this thing may have slipped a tooth on the timing gear. I had it running pretty good, then I killed it one day at a stop sign when engaging the clutch. It never ran right since. I know it's getting fuel and fire (massive backfires), and I've tried every tooth on the ditributor gear. I think it's down to the timing gear, whaddaya think?

Grandpa gave it to me, it is straight and original with about 90K original miles..
