Hello everyone!
I am wondering if there is a difference between a 1/2 ton 5.7 hemi motor & a 3/4 ton 5.7 hemi motor. The bottom end went in our truck & are having people tell us different things. Any hep is much appreciated!!
Thanks

I believe the top end varies depending on generation and model, but the bottem end is the same.

The only difference between the 1/2 and 3/4 tons will be the 1/2 tons after 03 will have an egr port on the passenger side head. Also on the 06 and up the 1/2 tons are equipped with MDS and the 3/4 tons are not. It is the exact same motor design wise besides the MDS lifters.
