in what sort of contraption might one find a factory placed 4BT?

 

You can find 4BT's in all sorts of stationary equipment and offroad applications. Case used 4BT's for years in various tractors both agricultural and in construction equipment and other manfacturers have used them, too. They are popular in industrial gen sets, too. Also, Frito Lay trucks and other panel vans, I'm sure, have been known to come with the 4BT backed by a Turbo 400.

 

cool, thanks. apperently they were used in marine applications too
