Hello

I have looked and cannot find the answer to this question.

I need to know if high gear on a 1983 300 SD transmission is direct drive or overdrive.

Thank you
Ken

i believe all mb of that era are 1 to 1 in fourth.

..I also have a 427 Cobra replica with an aluminum chassis.

That is what I was thinking but not sure

Thanks
Ken

Yup, 1:1 for 4th. No mechanical disadvantage on the trans with that ratio.
