Here is our stunning 4 carb blower top manifold, engineered to mount a set of four two barrel carburetors atop a GM 4-71 supercharger. The GM 4-71 is an excellent choice to get some more power out of your engine due to its commonality, low price point, and a plethora of knowledge and available parts for rebuilding. Originally utilized on the old Detroit diesels, these superchargers have been a favorite of hot-rodders since the 50s! Carburetors utilize 5/16-18 threaded holes for mounting. The manifold is under 2 3/4 inches in height and our friends over at stromberg97 supply all the necessary parts to setup a linkage. This piece is cast of 356 heat treated aluminum and wears the Nystrom script on the side. 

(THIS PRODUCT IS MARKED AS A BLEM AND REDUCED IN PRICE BY $75 DUE TO A SLIGHT MISCALCUATION WE MADE IN THIS FIRST RUN. THE GASKET SURFACE BETWEEN THE SUPERCHARGER AND THE PRODUCT IS ABOUT .200 INCHES SLIM ON THE INNER SIDES. THE PART IS STILL TOATLLY FUNCTIONAL AND THIS CAN NOT BE DETECTED FROM THE OUTWARD APPERANCE.
