My case w 20 b wheel loader has multiple motor issues, it was originally a case 401 bd engine. I have located a case 504 bdt. I know there will some exhaust and air filter relocation issues to deal with. My research has shown me that the 504 should be the same block as the 401. Any additional information about this possible swap would be greatly appreciated.
Welcome to HEF , Danny ! That is a very common conversion in Case 930 Ag tractors. It should bolt right in. You may need to do some modifications for the fan and radiator. Get on Red power magazine's website and I think you will get all the info you need. https://www.redpowermagazine.com/forums/
Thank you very much
