The biggest differnces I'm aware of are injectors got moved outside the valve covers after the 1 engine. The 2 engine also got rid of the ficm. Then they raised the fuel pressure which raised power and I'm pretty sure added egr on the d engine. The newest ones have a ton of emissions stuff on them.

lb7 is the only one with the injectors inside the valve covers
