Looking for feedback on 3500 Express and 3700 Open
#4
Both the 3208 and B series Cummins are parent bore engines, meaning they do not have cylinder liners. That does not mean they cannot be rebuilt however, in fact they are rebuild all the time. As long as the cylinders are in spec they can be honed and put back into service with new pistons, etc. if the block is damaged from overheat, etc then more than likely they are not rebuildable although some mechanics will sleave the engine.

They are both pretty tough engines, again it all depends on how they were run and maintained.
