Comparison between 3406E and C15 truck engines

You should talk to rollin coal. His mbn ecm was programmed by mr haneys. His actual name is Kurt.

 

the mbn can be built as a 6nz. better gasket seal's on front and rear structure's and oil pan. plus you have crank and cam sensor's so if one fails it will default to the other sensor and still run. the only issue is the wire harness from chassis to engine will have to be altered. the 5ek is 40 pin plug where the mbn is a 70 pin ecm. if you can just do an inframe the cheapest way to go is with the 5ek that you have in it. just spec it with the internal parts for a 550 hp.

 

Thanks for the Info
