Richard,
What timing. I was just thinking of contacting you to run some numbers now that my engine build specs are close to finalized.

Bore: 4.020"
Stroke: 3.48"
Rod Length: 5.7"
Cylinder Heads: GM Vortec 906, factory except for new valve springs. (not sure what line item to choose in your linked data page)
Intake valve dia: 1.940"
Exhaust valve dia: 1.500"

Static Compression Ratio: 9.013
Dynamic Compression Ratio: 8.187 (my own calculation)

cyl volume:723.806cc
chamber vol: 63.981cc (after milling head)
piston deck height vol: 2.288cc
piston dish vol: 18.0cc (not sure if dished is shown as negative or positive)
head gasket vol: 6.058cc (0.028" by 4.100 dia)

Carb: 650cfm single 4-bbl (Proform 67207)
Intake manifold: dual plane, (Edelbrock performer EPS 2716)
Exhaust: Hooker 1-5/8" full length headers w/ 2-1/4" Maxflow mufflers
Camshaft: Compcam magnum, pn 08-410-8, grind 260HR
Hydraulic Roller,
Intake valve lift 0.500, Exhaust valve lift 0.500
Timing copied from cam page, forgot what they all mean)
Duration(0.050) Intake:206.0, Exhaust:206.0
Timing (0.050-inch) IVO:-3.0, IVC:29.0, EVO:37.0, EVC:-11.0

Let me know what ever I forgot and I will re edit this page.
Results of this sim will be very interesting to me.
Thanks
