This engine is making very good power and the engineers are saying the bottom end has been built to last the long haul. They seem very confident that it’s gonna prove to be very reliable. With this power and more on tap with a lil tweaking some good clutching and the efficient skid in chassis platform these should rip. A well tuned assault 800ho has proven to give the doo850 a good run for the money. I forcast with this new 850(840) there is gonna be sore butts in the doo camps.
