340 cam specs?

And because people probably want to know what the software says even though we know input is wrong..

The model used for the above is Fill and Empty simulations.
Sea level. Air Temp 68* F, RH 0%
340 std bore, 10:1 CR, 77 cc chambers, Open Wedge Head, Flow numbers X heads posted by Shady Dell
Carb flow 660 cfm, Dual Plane Std flow intake, H.P. Manifolds with Mufflers.

And for further comparison here is how the modeling stacked up against two real dyno tests done in the magazines. Not that I fully trust the magazine reports but I think the trends and shapes are correct. Not sure of the full details on the Mopar Muscle build (compression for example but assume its 1970 based), or how the dyno was run(600 ?)
HR = Hot Rod Magazine 1969
MM = Mupar Muscle 2001
