1980 4 Speed gear ratios
What are the gear ratios in the 4 speed transmission for the 80...it went to a wider ratio but I can't find the numbers. Thanks in advance for the help.

Thanks for the response...I thought it was a Super T10 but the "M18" in the book threw me off..."M" for Muncie. The rear ratio for this is 3.07, right?

greg, the rear end ratio of an '80 is a 3.07:1 providing it's never been changed by another owner. Also, the transmissions are BW T-10's. GM for some reason kept that "M" designation well after the Muncie trans were not being use anymore after about Feb/March of '74.
