Engine:Truck Engine Specs for G63B, G54B, G64B, 4G64, 6G72, 4D55

As you view this page, please check for possible mistakes that I could have made.
Mitsubishi's engine coding is by far a crazy number & lettering system that can be
very confusing to everyone. We have tried to organize to our best these codes.
Send a PM to Bradmph and be sure to describe the problem in full.
