That should be plenty of cam Jim. I used a 222/234 Crane in my stock 400 and it was a nice street cam. You could probably go down one step to the SEH2024AL-11 and still be happy.
I ran both thru my "dyno" and they both have the same peak HP (300 @5500). The 2024 has a bit more low end torque - as would be expected. This was with Hughes recommended 9.25:1 CR.
