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.
