I agree on the flat hood, as always its a money thing.
Tuning is going ok, the Holley HP is really not the correct choice for a Hilborn set up even though that is what they sell with the injector assy, it only has 1 o2 sensor to tune the ECU, it really should have at LEAST a bank one & bank two base fuel map that the ecu runs on. when the engine heats up all those throttle blades move & changes the calibration, I hooked up my Innovate wideband through a channel on the Holley ecu so I can at least datalog both o2's side by side & can manually tune the right bank to match the left bank Holley ECU wideband. wide open throttle is not a problem, its all the very light throttle low rpm areas that are tough to tune with 8 throttles & one o2 LOL. it idles like a stock cam 440 hp, can run 1500 rpms in overdrive & lock up the converter,,,, smooth as glass. the Dominator Holley ECU has two o2 sensors but you can only pick left or right or average of the 2 sensors for the ECU to tune off of.
