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.
