Check my work-Chime in please

OK, can you move the piston back up to TDC, and then measure the CC's down in the block at that point? That will complete the data needed to figure this out. We can crosscheck this to the info given in the past for the Egge pistons.

And yeah, I expect the SCR and DCR to be lower with this info.... the Egge pistons are the lowest compresssion height of the available 4bbl 273 pistons.

How can he measure the area below the deck at TDC with a dome top if part of the piston is protruding above the deck?

It can't be done. This is exactly why the .500" method exists.

did you mean to suggest measuring how far down the flat part of the piston is from the deck height?

That can be useful, but the CC's are already measured using the .500" method. I guess it can't hurt to cross reference though.
