streetmaster intake?
hi
i am looking at intakes for my 390 and ran across the street master intake.
Edelbrock has this intake on there site and Summit doesnt have it in there catalog. Does anyone know the rpm range this manafold is suggested for?

It is a lower end manifold, however the tech at Edelbrock told me it was good to 5500. My son has one on his and he can get 5500 with no problem. They have'nt made that manifold in probably 20 years.

I traded my old junk bike for an old junk truck and it actually has one of these ancient Streetmasters on it. I can't tell what RPM it'll go to because there is not Tach (yet..haha) and everytime I give it full throttle the clutch just slips and slips......new one on the way. Seems to work well for me, although with such a bad clutch I can't tell too well. I wish I could get some specs on it.

Well when you just look at the design it tells you something. The ports are not large in fact relatively small which means velocity. The Streetmaster came out in the 70's when we had the first major gas crunch. It was designed for performance with ecnonomy. Of course we all know that when perfomance gets better we use it more and there goes the economy. Offenhauser came out with their Dual Port manifold at the same time for the same reasons. Instead of the X design however it was more of a typical high rise looking thing with each port divided in two, large and small. The smaller port worked off the primaries and the larger one handled the secondaries.

I've got one in my garage on the shelf. They are an OK, and just an OK manifold to use. I stay away from it because of the single plane design. Performer, and I'm learning the Performer RPM are much better intakes for across the board use.
