I am curious does anyone have any experience with a duel port offy I have a edelbrock performer but was thinking of trying a duel port offy on a very mild 360 that I am building thoughts thanks Mike

I have one for smallblock chevy in my leftovers from chevy days. I never used it. Looking inside it I wonder how it ever worked, it is a rat's maze in there.
I also have a brand new one for Toyota Land Cruiser that I intend to use one of these days............................plus a brand new Carter 9401 or is it 9410.

Steve Dulcich tested one in his 383 intake manifold shootout, that may give you a hint.

I would guess that the Performer will outgun it in every respect. Offenhauser was nearly dead when they designed that thing in the '70s. The company now is IMHO majorly dead, but like a vampire they keep moving. They do make some interesting intakes for obsolete engines, and we should be thankful for that. It's nice to know that a brand new set of Offy heads is still available for my flathead that's moldering beneath the trees.

Still, give it a try and let us know.

I have used ONE years ago, never again The added mass inside t6he manifold reduces the amount of air it will flow so it really hurts the motors, no help at all

Thanks Ill stick with the edelbrock I was wondering the idea behind it seemed reasonable mike
