Review on Quick Fuel Technology HR 780 VS Carburetor by Marcus Rash

I have this on my Dodge 408 (465 hp and 535 lb-ft of torque) and it feels strong and runs fine. Ideal for heavier vehicles with automatic transmissions and/or high torque engines. With my 10-11 inch vacuum at idle, I changed the power valve from the factory 6.5 to 4.5, which fixed the slightly over-rich condition at idle.
