Some more info for ya: Compression ratio is 9.4:1, Bore is 4.000, Stroke is 3.480, Rod length is 5.7".
I've read somewhere that the cam is like 194/204, but don't hold me to it. It should be around that area somewhere.

Thanks for the information, sorry for the delay, for some reason I'm not getting e-mail response from the board. I need to see what I did or didn't do right....
