Oh no I think I have a 3.09 4-speed, help!!

I don't unfortunately
I'm still building my car from the ground up
Transmission guys totally screwed up on the job here so I'm rebuilding it myself
If you're planning on shifting it up near 7000,there are some mods you need to do,and some optional ones, to get those big sob gears to slow down in a reasonable period of time.
And a lightweight flywheel helps too;this is a natural fit for the 3.09 low gear.
