Cam is Way Off TDC 900

1993 Rex/Regina with a replacement engine from hell.

I have been plagued by a no start condition for sometime now on a new purchase. I have spark and fuel. I tried some starter fluid but before a second spray I felt air pulsing out of the T-body hose. Puzzled, I borrowed a friend’s compression tester. Dry, 0, 0, 0, 0 PSI. Wet on number 1, 0 PSI. OK, shot rings, holes in the pistons, carbon on the exhaust valves. Leak down test is needed.

Pulled the valve cover to triple check TDC. No I already checked the cam mark, pulley mark and the cylinder location. All lined up! For what ever reason I pulled removed the valve cover and I am looking for “perky” per the FAQ. Cam lobes were not where they are supposed to be! I aligned the timing mark and removed plug #1 and removed cam cover from my ’95 to verify the cam lobe location at TDC and find the proper cam lobe orientation.

The photo shows ’93 with the cam location at #1 piston TDC/cam pulley aligned/crank pulley TDC. The cam pulley is not the adjustable type. What is going on?
