Olds Heads question 324

anyone have an idea on what the compression would be with the pistons in the picture?

 

My front mount I made to come off the 4 orig bolts under the pulley, and then out to the orig 32 rubber cushions on the stock 32 front crossmember.

If you need that pic I can take one, or I think I have some pics saved of stuff I saw on ebay...one was a saddle deal like the hurst SBC mount, and then a pair of maybe homemade side mounts similar to the orig Hurst Olds side mounts.

 

Those rockers are McGurk. I had several sets years ago.
