Optimal specs for a 351W/450HP stroker motor?

[timsullivan]

I just bought a Superformance roller and want to build the motor myself having built a few Chebys in my previous life. I'm shooting for around 450 to 500 HP and will be using a TKO 600 trans. Currently I'm planning on starting with either a 418 or 420ci stroker short block based upon a 351W and adding most likely either Edelbrock alum Performer heads or Victor Jr heads, probably a Torker ll intake, 780 Holley and MSD ignition. With the 60cc Victor Jr heads I can get flat top pistons running 12.5 compression ratio or with dished pistons, 10.1 in my short block assembly.

I'm at a loss on what cam and cam specs to run here and would appreciate any suggestions that you might have. Of course I want something with a lot of power but I don't want some totally wild street beast that is going to be a real pain to live with.

What are your thoughts on a cam and related cam specs and what changes in my build specs in general should I consider in order to reach my goal of 450 to 500 hp? What combination of parts do you see here that sounds all messed up? What better combination can you suggest? Unfortunately I’m on a limited budget here so aluminum blocks, FI and other exotic stuff are out of the question. Thanks in advance for any thoughts you could share I need all the input I can get right now.
