How do you determine deck clearance in an engine using math?

Stroke รท 2 + conrod centre to centre length + piston compression height.
Subtract that number from the deck height

LA 360 deck height is 9.6" connecting rod length is 6.123".

Okay, here we go with the Speed Pro piston that is a 1.660 compression height:

3.58 divided by 2 = 1.79.
1.79 + 6.123 = 7.913.
7.913 + 1.660 = 9.573.
9.573 - 9.6 = -0.027. This theoretically puts the Speed Pro piston .027 in the hole assuming the block hasn't been milled since new and matches the spec.
This does help!
That makes the KB 107 and the 232 pistons approximately .012 in the hole.
Thank you guys!
