318 stalls in Drive

Good point about the gas. It's non-ethanol, 89 Octane. The station is frequented by boaters and landscapers, so I assume it's fresh gas.
You did remind me of something. I'm fairly certain the converter in the 340 car is 2400 rpm stall.

Incidentally, I understand that automobiles and such are a system. Alter one component, it affects another, and so on. Certainly got a mismatch of system components, as pointed out earlier.

Replacing the converter is obviously an engine pull.
Replacing the cam is an engine pull.
I think I"ll pull the spark plugs.

Anyway, thanks guys for all the input. I'm on the East coast and it's about my bedtime. See ya'.
Yeah it's West Coast and we're still washing Mash here. And just so you know the cam is a manifold water pump and timing chain cover pull not a motor pull. You may have to pull some of the grill apart to get the cam to slide all the way out. And the converter is a transmission pull both of which should be take apart one day and put together the next. Unbolt and bolt back in. Not rocket science just a lot of dirt and Grease if you don't have your stuff clean.
Good night and I'll check out your response when I wake up in the morning LOL
