I was doing some injector research and came across a type that sprays a V pattern at an angle of 30 degrees to the centerline of the injector body. I believe an ideal injector setup would direct the spray at the back of the intake valve. One thing that I am not sure of is if the spread of the V will now direct the fuel stream to the sides of the runners before it gets to the valve. In our D-jet log setups the injector is aimed directly at the bottom of the short stub intake piece. I currently run with the 4 hole type - which seems to atomize the fuel better than most. See the link below for the spray pattern options.

I found an engine section diagram in the blue books (unfortunately only for a carb'd engine) and drew in the rough location for the injector. If my assumptions are correct then the angle of the fuel spray pattern comes much closer to hitting the valve. The electrical connector would need to the rotated to the drivers side of the rail (which I can accommodate on my custom rail). I may experiment bit this Fall/Winter.
Any thoughts?
Any one have an engine drawing section with the log manifold setup?
Thanks,
