cam or charger

[xgenralxleex01x]

I have a 93 4.0 and want the most RPM possible seeing as im going to only use ths thing at the dunes and probaly a 75HP shot of NOS. What cam should i get and whats your thoughts on my plan seeing as I am a rookie. THank you. Hope this isn't considerd a thread jack since were till talking cams?

its fine bro, i would get the 422, the 410 is more for better fuel eco.
