383 intake

I am building a 67 383, looking for around 425 horses out of it. The question I have is, I have a Offenhauser intake that came on another engine I had. I was considering using this intake, since I already have it, and would probably save around $240 over buying an edelbrock rpm. However, I dont know much about these intakes, all it says on it is 360, with a circle around it, and Offenhauser. Are these good intakes, or are they just a aluminum version of a stock 383 4 bbl intake. Will this intake be able to support my HP goal? Thanks guys
