There's an age old debate about which to use, and a lot of people think that just because the 4 banger trany was for the 4 cylinder car that it's going to explode if you put it behind a 5.0...well, they ARE weaker, but for a mostly stock 302, as long as you don't miss any shifts you'll be fine. I've got a friend who swears by them, he won't run anything but them. They're actually a cheap way to lower your gear ratio as opposed to getting gears. He runs low 13s in his.
