We recently upgraded the Kaufman heads to provide for larger flow (340 CFM with CNC porting) which resulted in our need to have a custom intake and throttle body assembly made. Visner Engine's is a local shop with experience in the NASCAR world and puts out an incredible product. They were milling the top of the intake out of this chunk of billet. Here is the CAD design of the intake. We are going to build a set of custom throttle bodies with the linkage concealed under the intake so the entire top will be smooth. The CAD shows one fuel rail per side, but we are running two per side as we will have two injectors per cylinder.
Here is a picture of the top that was just finished.
Here is one side rail being milled. 10 hours of milling each side.
