454mag Efi Short Runner Intake?
 

I am planning on buying the Arizona Speed & Marine Short runner intake manifold for the 454 EFI engine. Does anyone have one of these, does it work? They sell for $640 with exchange. They say it give a stock engine 30hp. I also plan on adding 38 pound injectors. Any info would be app. Thanks Bill

Yes it works, and you have mail

High Priority;

Do you have any first hand experience with this manifold? If so, what kind? Does the ecu need to be re-programmed? What kind of increase did you see?

Yes; We have run this intake with good mid range and top end gains. The ecu does need to be re-programmed to work. We see about 4 mph grain on top end and a lot better mid range torque.
