I used the spacers to turn the throttle bodies so I could use inline linkage. The fuel rails kind of wipe out the chance of using the bel crank style linkage like a sideways mount would require. So I used the 4500 top for the manifold and some 4150 to 4500 spacers so I could turn the throttle bodies. I don't like it but for now it is what works.

The Coils are run by the Megasquirt 3 Fuel Injection
