Had a gentleman call me last night and he has a 68 XR7 with a 4-speed manual in it. Says it's the original tranny and been rebuilt once. I have never actually driven a manual transmission car that old. Just wanted to get someones impression/experience/opinion on them. The 3 speed automatics are loud and have me rocking forward sometimes to help it into 4th gear (don't know why I do that) Is having a 4th gear quiet the tranny at all? I know that they are wide ratio which of course is not ideal for muscle cars.
