I found a 3/4 ton 76 with a 6 cyl 4 speed, what was most common gear ratio?(need axles)
4:56 I would think sence it's behind a 6 popper.
Probably 4.10's. 6 cylinders want some help off the line, and in '76, speeds on the freeway were'nt as high as now so low gearing was more common. OF COURSE, there is always the "special case" - no good way to really know unless you pop off the cover.
<font color="green"> 4.10 is most likely, but I believe that 4.56 is possible as well. </font>
Prolly a better than even chance it has 4.56's...
Pulling the cover is pretty painless, and then you'll know for sure.
or just see how many times the pinion turns with 1 revolution of the tires.
RPOs in the glovebox will tell you.
Chances are it has 4.10s. It might have 4.56s but since it's got a SM465 it doesn't need a whole lot of help getting moving.
Im sorry and I really dont mean to HiJack this thread but Wrath, you have got the BEST sig line Ive seen in a while! [ QUOTE ]
