All I need is 50 more wheel, if Afr's and a bigger cam and a monoblade can't get me their than I'm not going to waste that much money its not worth it! I'll just setup up the nitrous and call it a day.

AFRs are not necessary, read all the replies.

Well, I have the right castings they need, and they already have the right valves, guides etc. Mine are CNC ported, and flow pretty well, IMHO. For a 230//236 cam HR and I make 425rwhp/428 ft/lbs tq with 2800stall and 3.75 gears, I would say I am doing pretty well. I was looking into a solid roller and bumping the compression up, as I am at 11.1to1 now.
So, a 610-640SR, and 12-12.5 to 1 and a little refreshing of my heads, and I should easily get 475 rwhp. Change the stall and mid to high 10's?
The possiblilitys are there as the AI crew has shown.

a 398 is a 396 with a little larger bore.

Should be about 4.060" bore for the 398.
