Right, and that makes for alot better selection of springs. Mopars stock low installed height of 1.7" isn't huge in the aftermarket. Springs for them will cost nearly double what Chevy springs cost that are installed at 1.8"

As far as what springs to use that depends on the cam. Get your cam first and look on the cam card for the spring pressure requirements and match a set up from there.

So I probably won't be able top get away with the lift that I want unless I have the spring seats cut?

This is an area that I'm not very knowledgable on...
