I've got an 03 F750 and would like to do a repower.

It has a 24v cummins 5.9 right now.

Anyone have experience with the 8.3L and the DT466?

Is the 8.3 a wet sleeve? I know the 466 is.

I'm considering only mechanical engines.

I've driven both is similar specs. tandem axle dump trucks.. 8.3L with a 8ll and the 466 with a 13spd. The 8.3L walked all over the 466 similar weights etc.... But I'd look for a ISL!!! Its MUCH MUCH better. a ISL is slightly bigger but has a real jake compression engine brake. There is thread over on the TDR where a guy swapped a 3126 cat out for a ISL... i think there is a thread here on comp d where a guy p pumped a ISL... that would be my engine of choice!
