The Xtreme Energy XR280R solid roller (242/248) is designed for Chrysler 383–440 three-bolt engines, delivering strong mid-range power with a lopey idle. It performs best with about 9.5:1 compression and a 3000+ stall converter. This profile targets drivers who want a pronounced midrange while accepting a rougher idle character.
