Description: Fits Holley 4150 square bore carburetor's. (That means all 4 bores are the same size)Flange pattern 5.160 /5.620. 750 cfm (1.69") boresIncludes studs, flange nuts, One open and One 4hole gasket made with Felpro material2" tall Made in the USA from a carbon fiber PC blend. light strong and insulates from heat. After years of dyno testing and race engine building we found this is the best design.Adds mid range Torque and top end Horsepower.We tried "Super" 1" versions from different manufactures including the clones. We came to the conclusion they are just made to look cool. There spacers are not tall enough and the design is poor. Made for marketing purposes. If your engine gains anything from one of those over priced 1" spacers you would probably get the same gains from a standard inexpensive 4 hole or open spacer.Our 2 inch design Actually works by fogging / atomizing and evenly distributing the fuel much better than other designs. Its hard to see in the pictures the 4 round (Top) holes are blended into the 4 contoured holes (Bottom) with a very carefully designed radius shape.We ship within one business day many times the same day payment is received.Thanks for reading this
