My calculator says this:
Camshaft, Rod Length, and Altitude Correction to Compression
Your engine summary is as follows: Bore 3.367 inches, stroke 3.54 inches, rod c-c length 6.875 inches, with a static compression ratio of 14.25 :1. Your camshaft specifications call for an inlet valve closing of 75 degrees ABDC @ .050"(1.25mm) lift point.
Your chamber volume is 38.98 cc's. With this camshaft your dynamic, or effective stroke is 2.44 inches. Your dynamic compression ratio is 10.13 :1 corrected for cam timing, altitude, and rod length. Your dynamic cranking pressure, corrected for cam timing, rod length and sea level altitude is 215.17 PSI.
Pictures are looking awesome!
EDIT:
Looks like the intake valve is pretty close at TDC. There is a lot of piston dwell after TDC, and the valve will still be opening rapidly. Did you check it for clearance at 5-25 degrees ATDC?
About 1.5mm clearance is good, and it can go a little closer in a pinch. I woudn't go any closer than 1mm clearance.
And you can take into account that there will be at least .25mm-.3mm lash clearance added in when it's hot. Your closest proximity of piston to valve will be when it is cold.
I realize that you know this stuff, but I'm just nervously double checking everything!
