Well, I run a 4-speed (not sure if M-20 or M-21), so the trans cooler doesn't apply, but I figured I would work with what I have with minimal mods (college student budget). From what I saw on other forums, many seem to run with stock transmissions, so I figured I could too. Though I have been on this forum for a few years, I still consider myself very new to the hobby. I actually haven't driven my car yet (cracked 383, replaced with 305, still not registered), so I don't know how I will drive it. It's also my first manual trans car so I truly have no clue on my driving style.
Perhaps I am thinking too far ahead? Probably, but learning now will help me make better decisions when the time for something bigger comes around.
