Beast96Z, Can you check my calculations ?

With the calculator I posted, I get 11:8 SCR and 8:85 DCR. If the piston comes above the deck, you have to enter the - number.

You'll also need the formula for calculating IVC at .006". It's not on your cam card. That formula is : Advertised duration divided by 2, plus your ICL, minus 180. That will give you the IVC for the last blank. The site says just add 15 to .050", but that is horrendusly off, and basically a guess.
