s guesses)......
'72 350 with HEI in my K/5......not a DD at all....so I start it up frequently and drive it when I can....
Last Thursday..started up, warmed up...shut it off....

Friday afternoon....went to start and drive....two or three, what sounds like backfires, and the starter hung up in the flywheel.....got that fixed.... tried to start up.....

same thing a few backfire sounding noise...but no start...

I'm thinking....best case.....ignition module?
worst case....jumped time.....tomorrow I will pull the cap and check for that

I have no history of this motor...except that it's been running like a champ
until now....
