First test fit 5.7 truck engine

What year is the 6.4 intake manifold? I think I will have the same issue you have. Mine is a 2014 5.7 truck engine with what look like the same truck intake as your 2012 manifold.

Thanks,
Mike

I think it is a 18 or 19 . The manifold is an inch taller than the 5.7 truck manifold and the throttle body swings to the passenger side of the engine
