Cool Will any 6.1 HEMI parts improve 5.7 HEMI

Curious if anyone has swapped any 6.1 HEMI parts to the 5.7 HEMI, I've seen posts about the cam and that's about it, I'm wondering about the rocker arms intake with the TB even the fuel injectors and plug coils. Parts that don't involve tearing the engine down or out that can add performance. Has anyone done anything to this effect with good results?

I would also like to know about this and how hard is it to put a new cam in these engines? I bet it would be a pretty expensive upgrade for probably fairly small gain but I could be wrong about that.

With an intake swap I would expect to see top end gains with a loss of low end performance. Not really what you want for a truck. Bigger injectors are pointless if you aren't moving more air into the cylinders. Swapping rockers won't yeild anything either.

I have yet to see any cams (at least from Mopar) that are compatible with MDS engines. If you're not making mods to the heads and induction system, a cam just isn't enough bang for the buck IMO.

Just thinking that the 6.1 might have a better rocker ratio or maybe a better flowing TB just looking for parts that are already proven that would be simple to swap. Maybe find a complete 6.1 in a scrap yard to pull parts from.

Wonder if you could swap out a 5.7 for a 6.1 ?

What about the 3/4 ton's like mine that don't have MDS would I see any gains from a cam?

As I understand you can swap a aftermarket cam to a MDS Hemi with no drivability issues, I have read of swaps in some of the other "forums"

You would probably have to have a complete donor vehicle for the engine, trans, and ECU and someone with acess to Dodges DRBIII handheld scanner to program the little problems

Some parts can be swapped from the 6.1 into the 5.7 with no issues (just some time for the CPU to learn them). A 6.1L camshaft swap will net you approx 20RWHP.
