No, I don't recall if it had the specs or I would have them - might have been a "Fulper Secret."

There was another article done on the same engine using nitrous, 672HP. The cam specs are listed and may be the same for above.

Comp Cams Solid HR.
Duration at .020" - 285/Int, 296/Ex
Duration at .050" - 255/Int, 260/Ex
1.5 rockers - Lift .538" Int, .538" Ex (these numbers not clear, but under .580")
Lobe Center Angle - 108 degrees
Installed Intake Centerline - 100 degrees

No cam expert, but do the .020" and .050" numbers look true - this is what was shown in the article. Maybe backwards?

More specs on this engine included in the text. Keep in mind, these HP/TQ numbers were not necessarily accepted by others.
