Ok Mr Weld!

I got those measurements:

I used a mastercraft digital caliper to give me my readouts.

Piston bore size : 64.84MM (65MM bore)

Top of piston to bottom of skirt : 42.58MM (42.5m

Wrist Pin : 14.97MM (15MM)

Top of piston to top of Wrist pin : 14.64MM

Top of piston to center of wrist pin : 22.12MM

I think I gathered up 0.072" clearance at TDC from the piston top to the edge of the cylinder head where the piston would first contact if it centered too high.

Can I plain 0.035" off my culinder's deck to gain a little on my CR?
