In general for me, 4, 6, or v8 (never done a v12...)
* With the gear or sprocket ON- grab and spin as best you can
* When you let go- it should spin on its own, at least a little bit (say 1/8 rev or 1/4 rev). I'd like to see it go a full rev around or near that, but I'll call it "done" if its 1/4 rev of free spin.
* To me, if you grab the gear and spin it and there is NO free spin after you let go, its too tight.
* Ive heard people SAY that if the cam will go in, its ok, it will loosen up on its own, but I'd be too afraid of spinning a bearing or galling to settle for that, unless the engine was expendable and I had several spares.
Willys F-head??????
Here I was thinking this was the "all Chevy Six" section, but its not. Congrats on keeping a rare old inline running!
