Wanna see what winning the lottery looks like?

Had a T/A 340 in my 70 Duster in 1981 and was adjusting the timing and carb, had the air cleaner loose with the nut sitting on top of it. I moved the distributor while it was running and goosed the throttle, it backfired, the air cleaner went off the side of the engine, and the nut hit the hood and went right down the carb. The engine quit and white smoke came out the drivers sidepipe. That was the end of the 340. I took the intake and head off an there was a valve stuck sideways in the piston. You indeed got very lucky!
