looking for cam and pistion ideas.

The more cam you throw at it the more compression you can run, in general.
For 92 octane an iron headed engine can run 10-1 and nearly any aggressive cam.
Generally speaking.
The old MP 440/500 cube create engine ran a advertised 9.0-1 and a 292/.509 cam for an advertised 505 HP.
To make use of 4.88's and a 28 or 29 inch tire, you could use, for example, the MP .557 lift cam (approx. [email protected] duration and as small as I would go) and larger. The .590 lift cam (approx. [email protected] duration)would work on a 10-1 iron headed engine. Though a fully ported iron head would be more of a matched part as a stock head would not be. (For both cams.)

This is in general since there's more than 1 way to skin a cat.

Considering it is a stock head, look into split durations to assist in better breathing and performance.
