3406 b or c question

Hey fellas. I have a 1994 t800h dump truck. It has a 3406 in it but trying to figure out if it’s b or c. It’s a 3zj44731. Problem is when I pull it up it says can be either b or c. If it helps it’s got the 12 bolt head studs and the pointed nose cone cover on pump. Thanks for the help. I can pull the block number if needed. I also have another question about adding power to this truck. Should I make that a new post or throw it up here.

 

God no peec. lol. It’s a 7e5888 pump.

 

Ya I got kenworth dealer to pull it up. Man all those service ppl are lost. Ha. Long story short they also said it is a c model. They didn’t tell me if it was a peec before or came mechanical. I see some of those c model generators made some big hp. Wonder if they got stronger internal components then our truck engines. I sure would like to see the full build on my engine. See what pistons I have etc.
