Small block intake manifolds...

Hey guys and gals ! I am building a 318 stroker (hasnt decided on 3.578 or 4.00 inch crank yet) and I was wondering what would be a good manifold. I have cut it down to 4 that I think would serve the purpose and get me the horsepower I want. I am hoping for 450 +/- horsepower in this lil combo.

The manifolds that I have picked so far are the: Weiand X-CELerator, Weiand Stealth, Edelbrock RPM Air-Gap, or Mopar M-1. I have never seen any Weiand on a mopar yet and I am curious at how well they perform. I was looking at the "basic operating rpm range" of all of them and the X-CELerator is claimed to have a 1500-7000 basic operating rpm range or Borr for short. The Weiand Stealth is claimed to have a Borr from idle to 6800 rpms. The Edelbrock comes in with a 1500 to 6500 Borr. I didnt get a Borr for the M-1 however so forgive me.

I plan to set the rev limiter between 6500 and 7000 so which of these manifolds would give me the most horsepower but also a flat line of torque since I will be running on the street quite a bit. Well any help will be greatly wanted and thank you all!
