the DT466 is made by international, and the 3126 is made by CAT. i am pretty sure that the DT466 is a sleeved engine, while the 3126 is not.DD

The DT466 is a sleeved engine...meaning that it can be rebuilt at a cheaper cost (when the time comes)

Both are 6-cyl units.....both are good products

The DT466 has been around for a while

You can't discount the Cat is the standard in the industry....

IMHO, the CAT matches better to an Allison 1000 or 200 series trans while the DT466 seems to perform on the series 3000 Allisons..
I think it's in the torque at certain RPM ranges.

I agree with Taz. Internationals are much cheaper to rebuild, but cat out performs them. Better torque and no match when it comes to top end.
