My motor does not respond to changes in the intake system. My fuel system is good, my ignition is good, etc. I have changed camshafts 3 times, non are substantially better than any others. I cannot beleive that between 2 different brands, and 3 different grinds, none of them are better than the others. I changed intakes, went from a tall professionally ported single plane to a home ported short single plane, and it ran exactly the same; same 60', same half track, same ET, same mph. I changed carbs, went from a 950HP to a 1050 dominator, and it still ran almost exactly the same; 60' slowed just a touch, et was the same with a little more mph. I think I could make it a little better with some more tuning, but not enough to make the motor run anywhere near what it should. It does not miss, or sputter, or not pull hard, it just doesn't run fast or respond to any exterior changes. I am thinking either my headers are too small and causing a restriction in the system, or my convertor is junk and it doesn't care what the motor is doing it's only going to go so fast.
The guys I got the motor from were running headers much bigger than I currently am, and I think maybe it is because it needs it.
Am I barking up the right tree for a change, or am still looking in the wrong areas?
