Rumble the cam was from Hughes, 236/242 @ .050 and in the .580's IIRC. The heads were Edelbrocks ported by Curtis Boggs. Looking back I think there was more in it with a good flat solid and more carb.
Don it would be interesting to see your new engine ran with the Airgap and an X-Cellerator. If you dyno it and want to borrow my Weiand just let me know.
I don't want to sell it though. lol
