Hello, everyone. I have a 1974 torino with a 390 fe and an fmx trans that originally had a 302 on it. I want to experiment with shifting it 1-2-d instead of keeping it in drive just to see if that works better for me. I have no idea the basics of how to do it, though. I'm too afraid of wrecking my transmission or engine to try on my own. I've heard that a good place to shift with an fmx and 302 is around 5k, but that's all I know. My 390 is very mild, only upgraded with a hei distributer and 4barrel carb+intake. Whats the worst that could happen if I shift to early or too late? How do I down shift? I know I probably sound like an Idiot, but I would appreciate someone explaining all this to me so that I don't hurt my drivetrain.
