Is there any intake manifolds or pistons for the 5.7 hemi, and what are the best headers? What is the stock CR?

 

Well, you might be able to get the 6.1L intake to fit if you did some modifications...not 100% sure.

Ross currently makes pistons for our truck. I've heard JE will custom make you a set if you call with your specifications.

I have the Dynatech SuperMaxx long tube headers. You are going to get the most performance out of a set of long tubes, but you'll also be paying more. My vote is for Dynatech...though others are just as good.

Stock compression ratio is 9.6:1 for the 5.7L Hemi.

 

Rumor's of some forged pistons out there for the hemi but I can't find anything substantial on it. The 6.1L intake is the only other one out there that I know of.

As for headers, I also have the dynatechs.
