Oh fellas....brings back ol'school shit. It's called powershifting, matching rev with syncros, slamming all four gears as you go, redline, let off gas and slam it. I had a 352 Mercury in a 42 Ford pickup with a crash box four speed (shaved off every other gear tooth), slipped like butter. Unfortunately on our first test drive going down hill we had a slight accident. We left the hole in the floorboard open after we dropped the tranny and hooked up the ujoints. Engine sounded so good, custom headers, then the front ujoint broke off from all the torque....very ugly. Really.
