318 stalls in Drive

Well, it's been almost a year since this thread was active. I"m slow. I know.

Replace the cam, they said. It'll run fine, they said.

.
And of course , you guys were right. So actually it was late last summer when I got around to it. Bought a new camshaft / lifters. Made the swap in one day.
The camshaft is the OEM profile. It was cheaper that way.
Runs just like any stock truck. Idles nice. If I recall,17" hg vacuum at idle. Throttle response is great.

The only drawback is the exhaust note. With the old cam, the exhaust would cackle like a dragster. Much lower decibels of course. Now the exhaust note is a very mellow, low tone.

Thanks again, for all the help.
