problems with Ford's version of cylinder deactivation. From Accounts, there were more than
a few spectacular failures. so it was decided to add some power and efficiency with a generous
OHC design that incorporated big valves and ports along with variable cam timing. The engine
was a compromise that never really lived up to its full potential and while it worked well in the
F250 and F350, ot failed the reliability test for medium Duty trucks, it just wasn't big enough
for hours of sustained loading that would come in the bigger commercial trucks.

Probably why a lot of US pick ups end up being converted to 6BT Cummins diesels, particularly now, given all the tune up options.
