My Transformation 5.7 Gen 3 in 74 Dart Sport

It is not very easy to come up with spec for Mopar Performance parts for gen 3 Hemi's. But that being said, the springs are the ones that come in the stage 2 scat pack kit with the Comp 270 cam(spec's, Comp 201-426-17 270/283 advertise 222/[email protected] .615/.609 lift lsa 115*) this is a larger cam then the Hell Cat cam. These springs are also recommended for the 6.4 cam swap in the 5.7 Eagle, which is just slightly smaller than the Hell Cat cam. Springs should work well for what you want to do.

So I shouldn’t have to replace shims and retainers? I just ordered the kit in the picture but wondering if I will run into a height/spring bind if I don’t put in smaller shim. To me, best I can tell, it should be as easy as old spring out, new springs I ordered back in. Swap cam, have the MDS turned off in programming, and push a new tune.

I make mention of Hellcat cam only because I think what I may do is go down the road of this 6.4. Then when/if I see lifter issues, I may swap with HC cam, MDS lifter delete, and a little boost. And it sounds like the springs I ordered should handle either scenario.

Does this all sound about right or I have missed something?
