Block is an early small block Chevy, not the later block with the cam thrust plate. Cam and crank gear are in perfect alignment (checked with the intake on and the distributor in).

Seeing the cam lobes are ground with a slight taper so the cam is always being pushed to the rear of the block.
Cam button is a waste of time and money. I have built a lot of circle track engines over the years and on flat tappet cams they need no cam button as I have never seen any issues not using one.
