Question swap 1977 dt466 for a 1993 dt466 without changing anything else

Hi i have a 1977 international dt466 that sat with water (no coolant) in it for a couple winters. I started it up and it water started gushing out of the side of engine. I was wondering how hard it was to swap engines with a newer 1993 dt466 or if it was even possible without changing transmission or anything?

although the engine might be ruined you might want to check if it is frost plug that came out.

good luck
later j

If a freeze plug blew out and it was not run until overheated, should be a cheap and easy fix. On the other hand, if it froze hard enough to blow a freeze plug...there could be other issues like a cracked head or block. But it is certainly worth examining to determine just where things stand.

The 77 and 93 are almost identical. As long as the 93 isnt an HEUI engine you will have no problem swapping.

From what I've heard, you'll want to verify what transmission the new engine was paired with so you don't run into bolt pattern issues during installation

All that would be necessary would be to swap flywheel housings

BTW the newer engine is the better engine, it has roller lifters and has more HP

A bit of caution is in order here.

DT466's were offered in a wide range of HP ratings. Make sure you don't exceed your transmissions capability. IE: 245hp in front of an AT545.

245 hp is really pushing it for the AT545. Generally they were not fitted to any engine making over 210 hp.

The number you really need is the torque. The spec for transmissions is maximum input torque, and not hp.
