Looking for 273 piston and ring options

Here's the closest I can come up with. I should have tool more shots. I just found another shot on another thread here on FABO. I don't know fore sure but I would imagine the pin height is different between the oem's and the Egge's. It would be interesting to have some one measure the compression on a virgin HP 273. There have been many threads about this here but I don't recall anyone measuring a unmolested engine. Mopar claimed 10.5:1 but how close to that figure was it really.
