MBHD, As you stated in ( Blowen & Inj.) forum if a "Race Pump" could be used.
The Stewart "Race Pumps" for a V8 are a great design, but on a V8 the pump uses a pushrod that is moved by the cam lobe and works on the pump arm; on a six the arm rides on the cam lobe itself because the cam is very close to the pump.
If you look at a picture of the Race Pump it has a short plunger sticking out from the gasket surface and maybe it could be extended to ride on the cam lobe.
This would be a great setup.
