Re: Stock gears???
Rear gears were different depending on transmission, engine, and you could get optional gears. Look on glove box door--might help. A 72 C10 2wd V8 auto----would usually be 3.07 ----a 4 speed would be 3.73. Now that's the most common build. A 6cyl auto or 3 speed could be very different.

Thanks, HUCK! It's an automatic. The gears feel more like 3.07 or 3.08, which I had in my Nova. I just wanted some confirmation. J

Re: Stock gears???
I was told that L6/250 or L6/292 came with 3.73's. I always take everything with a grain of salt, but have no reason to believe otherwise on this one

Re: Stock gears???
My books show 1971 & 1972 1/2 tons had 3:73 "standard" with 6 cyl's and 307 v-8, and 3:07 "standard" with a 350 and 402 big block. Of course either or could have been ordered. Standard gears should not be listed on the option sheet.

Re: Stock gears???
The standard gears would be figured with a 3 speed manual tranny.
Most 4 speeds got a 3.07, as did the automatics. (we're talking 1/2 ton here) |

Re: Stock gears???
Most c-10's with 283 to 350 with automatic trannys came with 3:08 gears in the rear. Trucks with v-8's with manual trannys came with 3:73's. The straght 6 equipped c-10's came with 4:10's in the rear with manual trannys. Yet to see a straight 6 with a auto tranny.

Re: Stock gears???
that's not acurate. All 3 speed trucks (except big block) had a base gear of 3.73
the only 4.10 gears that came standard were with the overdrive trannys which only came in trucks with 307 engines, or smaller. 3.07 gears came in all automatic trucks (again, non big block) with V8, and V8 with 4 speeds. I am not positive of the inline gears other than 3 speed off the top of my head, but I'll seee if I can't look it up here in a bit. |

3 speeds, 4 speeds and automatics. Every Big block 1/2t I have had had 3:07 gears also. The smaller engines had the steeper gear. This has been true in all the 100 or so trucks I have had. Now this is just my 2 cents worth too.
