What would the deck height be on my '72 350 using the below pistons? AFAIK, my head surfaces have not been modified at all. Also, what is the factory deck height? .020? Thanks.

- Sealed Power Speed-Pro flat tops
- Probe SRS +3cc

EDIT: Is Compression Distance (in) the way to determine ~deck height? If so, I am not sure how to translate that into a 0.0xx figure.

I am trying to determine which pistons above I should order to get 9.5:1 CR, and w/o modifying my head surfaces at all.

 

With the pistons in the engine now, you have to set the piston on TDC, and use a dial indicator. That is the only way to know with your stock pistons.
With your new pistons, you have to mount them on your rods and install in one hole and take a measurement from there.
