The intake duration should have 219 intake duration or less with a decent split and on the more technical side a valve overlap of around -5 to -8 and IVC around 42. Shops likes Texas-speed sell a package where you can order everything you need to swap the cam.

I'd try to keep the LSA as low as possible while maintaining at least -6*, and the IVC in the 35 to 42 range depending on what rpm range you want to see the most gains. IMO a nice cam that comes to mind is a Crane 216/224 114lsa, lift .585"/.585" with a IVC of 37, but like said it all depends on what going to be ideal for the individuals needs/wants.

I apologize for my ignorance, the lsx series engines are new to me. I worked on sbc's though. Idk whether they are completely 2 different animals or kinda similar in some aspects.

This must be a emissions legal car unless I can somehow get around it.
