Chevrolet Ring & Pinion Ratios
 
I thought I would share this here.
One of my projects this year was to help a friend find the proper rearend for his car at various local swapmeets. As our hunting continued,I noted all the variations within the different gearsets themselves.
I started to compile a list of the different Ring & Pinion tooth counts for Chevrolet applications. Attending Jefferson last week was the perfect library to finish the remaining counts on my list.
If anyone has more tooth counts to add,please do so.
<u>Pinion-Ring</u>
9-------37=4:11
10------41=4:10
11------41=3:73
11------39=3:55
11------37=3:36
12------41=3:42
12------37=3:08
13------43=3:31
13------40=3:08
14------43=3:07
15------41=2:73
16------41=2:56
