The 850 is a bigger stroke same bore and with new fuel systems like direct injection meeting epa standards is not rhat hard with more CI. Example look at ford and GM tue eccoboost is a small turbo engine, coyote is a small NA V8 capable of big hp and the GL LS is big cube old school push rod V8 all pass much tigher emmisions standards. When dealing with epa you emmisions standards are not taken at WOT same as car wot goes into open loop. Imo cat has been working on this engine to perfect it for years and they didnt expect doo to come with the 850 and because hp is on par they are going to stick with this cuz they have allways been top of the class reliability.
