Good point Terry!

With a 30/70-70/30 valve timing you have 185-190 psi across the board. Now with a 26/56 timing, the intake is closing 14* sooner. That will increase the cylinder pressure greatly. That's why I am thinking it would be, well over 200 psi with a 10.25:1 compression ratio. As davel had stated, a few degrees of cam timing, goes along ways.

Ben,

That is good thinking on your part. You just may have a real peice of history, on your hands. Who knows? I like to see that you are willing to give someone else a shot at it......
Once again, good job Ben!
