Thanks for asking your question. I will try and help you out.
The biggest difference is the FMM is a 24 volt ecm where the KAL is a 12 volt. To use it. The ecm and electronics of the FMM will need to be changed.Please reply back if you need more help or have more questions. I am happy to assist.

do you have any experience with these fmm engines...they all seem to have low miles & higher HP...do you happen to know what use they may have had in the military. thanks
Technician: Cat Man, Cat Engine Expert replied 4 years ago
they were used in several style military tactical vehicles. The iron in it is the same as the Kal with an hp of 275 or higher. If your KAL is less than 275 hp. It has different iron.

Customer reply replied 4 years ago
My Cal has a rating of 275. When you say iron does that mean the block Or other components. I had no idea that the sub 275 were that much different. Thank you so much
Technician: Cat Man, Cat Engine Expert replied 4 years ago
You are very welcome my friend. I am happy I could help.
By iron I mean pistons, camshaft, turbo, and injectors.
Please reply back if you need more help or have more questions. I am happy to assist.
