Camshaft help.....340 Dart Swinger

The FIRST thing the OP needs to do is STOP and degree the cam. It needs to be in at 100-102 and start with that.

Dot to dot means it can be anywhere from 98 to 118.

You start at the beginning. That is degreeing the cam. He's willing to do the work to install a new cam, so why not fix this one?
