what is the biggest cam u can run and still make good hp in a forged 6.0. i want a very noticeable lope. . and what set up will i need to buy for 14psi! thanks for the info.

 

You can use any cam you want, but some do not work as well with the turbo.
On the last 408 we did with a turbo, we used a 232/228 .588 .595 114lsa. It had some lope, but not excessive.
We have used 224/230 on a 112 too. Still worked very well.
