The 3408 engine was weak compared to the later 3408B with the longer block and larger bearings. Kind of interesting
the 3406 rated 300kw while the 3408 was generally rated about 315kw. Cat really did not have a good engine in the 400kw rating. They would even bring the 3412 down in the 400kw rating. Real hard to find a Cat 3408 block.
At least Cummins had the KTA1150 that would produce 400kw without having a rod come out the side like the 3408.
Even in the later 3408B Cat seemed reluctant to bring up the power rating. I might favor the in line six engine as I think the Cummins QSK23 inline six is a better engine than a V cylindered engine. The Cat 3500 series might be ok but when they are brought up to 1800 rpm then more holes in the blocks. Yet the Cat D379 and D398 (which are a heavier built engine than the 3508 and 3512) will run about forever at 1200rpm.
Cummins 855 are like the Cat 3406 good motors and you can still buy a runner for $2000. | |
