Camshaft help.....340 Dart Swinger

Personally I think it is a bit much cam for a stock converter and 3.23 gears. Stock tire or not.

It probably is. But, if the issue is in the crank, or the timing set and he just installs a new cam without degreeing it, he may end up in the same boat. He can get 97% of what he wants if he moves the ICL ahead some.
