340 Static Compression Numbers and Test Procedure

Right mine is way way off like 50 degrees. A piston stop method with a degree wheel takes me right to the point of yanking the dam thing and tearing it down and putting a new known cam in and lower comp pistons..........I think I am almost at this point then.....
I just saw this.... could be an old damper. On pre-70's, the timing marks were over on the right side, and the scribe mark was in an entirely different spot when #1 was at TDC. It was waaaay over to the right (CCW) from the 70 and later marks.

So is you timing 'tab/marks' on the right (passenger) or on the left (driver) side of the car? And where is the scribe mark on your damper when you are approximately at TDC? Give us a scribe mark location in an 'x o'clock' type of way.
