Cam and Stall Convertor
Now wait a minute guys, his 318 is stock and your suggesting a big cam? IDK about that move. It doesn't sound to good to me.
Budget now, big money spent later, well, I would not be swapping the used cam into the new stroker, that is for sure. It probably wouldn't match the new combo anyway.
You stated (OE poster) that your trapping at 5K. With that cam, the XE262, your trapping a hair low, but that ain't so bad either. A move to another gear ratio to adjust that now would only, most likely, be a waste of money and time since the new combo will want more gear. And a lot of it.
