Camshaft install
 

I just put my cam tower on the left side and torqued everything down to spec. I installed the camshaft in the housing and it does spin with out binding. I also installed the other camshaft in my other housing which is placed on the workbench not installed to see the difference. That one spins a lot easier. Should I be worried?

Hard to say, unfortunately it's a feeling...

Did you try to invert to see the feeling difference?

What else was done to the engine? Were the heads trued/flycut at the head gasket area? Were the cylinders replaced? Were the deck heights all the same?

Thanks for the replies. I ended up talking to Tony (BoyT911sc) who calmed my nerves. I think I was a little overly nervous with the smoothness of the spin of the cam. It's hard to determine what's right when this is your first build.

Cams are shafts and can have runout (not straight) and if so, can hang up when manually rotated in the cam housing. Good catch. A set of V-blocks and a dial indicator are basic tools to measure shaft runout. If it's off, a camshaft rebuilder or perhaps an automotive machine shop can straighten it fairly easily. One of my reground-to-964-spec-cams was out 0.004", but was motivated back to specs. It required more technique than hi-tech machinery.
