Damn it, it does say **** 
(sorry Allan ) Thought I was in the Mustang forum I guess 
OK, the image above does have detailed cam specs on my exact cam (F14-112)
Now I need to find the best (read easiest
) DCR calculator.
I'm running stock pistons, rods etc and 62cc heads. Gaskets will be .054", .045" or .040" depending P to V.
I know a few weeks ago I was rading all about calculating DCR, but now search only brings up a couple of posts. I have the calculator from the advanced tech section, but need to convert .050 nnumbers to .006

Thank you Patrick.
Edit: that's an f13, you don't happen to have the numbers for the f14? I know they are close, but I thought they were different lobe designs???

Hmmm, I come up with 8.51DCR and 11.2 SCR with a quench of .038"using a .045 gasket 62cc heads, -.007 out of the hole, advertised duration of 283/285 @ .006
throw in a .054" gasket and the DCR drops to 8.32, but quench is .047"
I wonder how that will do on 91 octane pump gas???
I need to check the numbers and run it again later.

The tighter the quench, the more "octane resistant" you combination will be. Take my car for example: I've got 11.5:1 SCR and 8.73:1 DCR, yet I'm able to run 30 degrees of timing with 0 knock at peak power. This is with 93 octane. See, because my quench is tight (.030"), I'm better able to run lots of DCR and timing without knock.
You can make more power with less knock on 91 octane with a .032" quench and higher SCR/DCR, than a .047" quench. Been proven too many times to ignore. Quench is your friend. Compression is your friend. In your case, I would recommend a .040" gasket. You will be even more knock resistant than with the .045" gasket (even though your SCR goes up).
