If you look at the RPI engineering web site you'll see that they actually recommend a Weber now I think. The Edelbrock and Holley setup is awkward to tune and possibly overkill but I don't know what other engine mods you are planning. The su's are good for enough power to destroy your Borg warner type 35 so if you are going mental you should consider doing something about the gearbox too.
Plenty of info on here under search.
I can't recommend doing you tube searches highly enough - it's quite possibly the best library in the world for finding stuff others have already done. Rpi do regular videos where they talk through these kinds of mods to the v8.
Hope that helps! - appreciate you might have only wanted a supplier recommendation!
