That is a killer set-up Eric, and great numbers for a safe tune.

You dont happen to know all the numbers I could plug into the ananyzer you used for a stock block.

I have a stock short block with 54cc chambered heads. I am thinking my compression is around 9.5 to 1

Thanks, Dark.

I think the stock numbers are as follows (someone please confirm):

4.000 - Bore
3.000 - Stroke
5.090 - Rod Length
4.100 - Gasket Bore Diameter
0.041 - Gasket Thickness
1.605 - Compression Height
8.206 - Deck Height
3.995 - Piston Diameter at Top Ring Land
0.175 - Distance from Top of Piston to Ring Land
4.600 - Total Valve Relief Volume (cc)
54.00 - Combustion Chamber Volume (cc)

If you put these numbers in, you get 9.85:1 compression, which sounds about right.

Jeff might be able to chime in and let us know if these numbers are accurate for a stock 5.0 (except for the 54 cc chambers on your heads).

Hope this helps,
E
