Original motor was NHC250 but I've switched it out to a turbo'd nhc350 due to lack of power in the fields and soft ground......now that engine is a bit weak (it was bought used) and needing attention again after four years running that engine. I see the BCIII's are still holding a price yet and I see that at Adeleman's the 6CTA's are fairly affordable. Anyone ever go to the 6CTA (8.3L) as an alternative Likes? dislikes? does it even bolt in well?
