Have been researching the Edelbrock SY-1 Intake manifold. Found a copy of the instructions on another site. (attached) Instructions list 2 GM cams recommended for use with the intake, #334096 & #334094. Naturally, I became curious as to what the specs are/were for these. BUT, they seem to "ghosts". I cannot find any mention of them, other than people asking the same question. Anyone here know anything abut them? And, yes, I have introduced myself on the appropriate thread.
