MP .528 Solid Cam Upgrade???

The single pattern grinds work well with ported heads. If the porting is good, a split pattern is t needed but helpful for more power. The split paten cams were designed to help the iron head, ported or not.

Choose the cam by the duration, it's power band, where it "cruises in" with as much lift as the head can handle. Go on line to a rpm calculator to see at what (on theroy) your cruise rpm is with your tire diameter, gear ratio and a 1-1 trans ratio. Which the MoPars have.

Your cams power band (begining) should be at least 500rpm's below that.
