Proposed 400 bb build, cam recommendations

If you are running nitrous you want a 112+ LSA, at least 110. That will hurt your cranking compression though, so don't go too crazy on duration. I'd keep it [email protected]

One cam that would work, and i've used it many times is the 284/.528/112 MPP cam.
The cam in my 360 mag adv dur ex 286 Int 274. 512 lift\498 113.5 lsa
