designed By Smokey Yunick, built by Edelbrock. not many made. this one looks like it has been set into a SBC valley but never bolted down. PO has probably used a Dremel like tool to etch a better seat at each end. intake top looks like it has never had a bolt in it. runners have been epoxied in at ends to help direct fuel flow. 2 homemade gaskets included. own a piece of history. $700 + shipping to the lower 48. thanks, mike roman (the junkyard pirate).
