J20- j2000 axles

What gear ratio could I expect to find in a mid 70 j-truck with a standerd tranny?

i know i've seen this info somewhere, i just can't recall right now if i come up with it i'll try to get a link here.

Paul or I just needs to know which tranny with which engine.

Oh Fawk it. Hold on.....


You asked about mid-70, so I looked at a 75. If you find one you want, let me know the specific year, and I will tell you what my book says.

J-10 6 cyl - 4.09:1
8 cyl - 3.54:1

This won't make sense, but is how it is written

J-20 all engines 3.73:1
J-20 option for 360 - 4.09:1

Thanks, I thought I found a set in a junkyard but found out the rear axle is gone
