Hello,you may still be able to get a set-up/info/tech sheet from Edelbrock for your SY-1 manifold.I have one of these manifolds,like brand new,and asked for the tech sheet and they sent me one,no charge.Car Craft magazine did a full write up on this maniflod once,way back in the 70's.I believe Smokey himself also gave some info on this manifold in Hot Rod magazine also,once upon a time.These intakes are quite rare and NOBODY knows anything about them.Smokey says they are indeed touchy to set up but once you get it right you will have one BAD ASS screamer.Start with a Holley 850 double pumper,PART NUMBER-4781 and go from there.The gasket that seals the top to bottom will have to be made from scratch if you need one.Good Luck.
