Lots of low end power. Pulls every bit as well as a 12v cummins down low and has good acceleration up high. 8.0L (488ci) 300hp @4200RPM and 450 ft ibs @2400RPM. Very esay to maintain engine. Has a very unique exhaust note. Doesn't sound like a V8 at all, very loud, nasty, and noticeable. Also 8.8-11MPG seems to be the norm.
