Losing my mind trying to get this 360 to run right

You cannot really check cam timing on "spit overlap" because most modern cams "are not." You'd be much better off checking balancer degrees on no1 intake opening, which will be somewhat BTC, just like timing


That is, get the cam card and pick something like intake opening, get your TDC checked (above mentioned piston stop......one of my favorite things to check.)

Then either get degree tape or otherwise mark the balancer. You can "rig" an indicator for a little more accuracy right on the valve, but this ought'a tell you if it's within 4* or so
