Engine 93 Cobra loses spark>>>>

351 uses a 5/16” hex shaft, while 302 is 1/4”. The 351 shaft is also longer.

I don’t even think you could put that combo together and have it run, but I could be wrong

Exactly what I was thinking.

My thoughts, since the 351 shaft does not fit into the 5.0 distributor hole it was riding on the end and slipping causing the distributor to stop/start turning and shut the car off.
My question is if it don't fit the distributor and fits the oil pump is the oil pump wrong?
Just thinking out loud.

The shaft fit into the oil pump,but the distributor end was different. However,the car had oil pressure. You figure if it was skipping it wouldn't, and the car didn't have a miss either. Weird.
