What is it? C20
This is my first post on this site. I think this site is the best thing since sliced bread. I just bought this truck this past weekend. Here is the story behind it. The guy who bought this truck new in 1971 gave it to his grandson about 3 or 4 years ago. The kid sold it to a buddy of his for 200 bucks. The kid who paid 200 for it gave it back the the grandson. These two arn't very smart, they sanded the pait off the truck and disconected the fuel tanks and other stupid stuff. The way I found it is that a guy my dad works with is the grandson's step dad. The grandson needed money so I got it cheep. What I do know is that it is a factory big block A/C 3/4 ton truck with 3 gas tanks. I was told its a Cheyenne but Im not sure now after seeing it. I am also not sure what engine is in it. I thought after 1970 Chevy started using the 402BB. But the glove box says 396BB. Is this because it has a January build date, and they used what was left? The glove box also states it is a Custom Sport Truck. I thought that after 1970 they did away with CST? I tried to take pictures but it didn't come out so I will list the opitions on the glove box door. I would like to find out just what all this thing is.
LEFT SIDE: MODEL #CE20934 1B85AB BELT MOLDING 1F51AC FRT & REAR SHOCK AB 1G50AE HEAVY REAR SPRING 1L47AG 396 CU IN V-8 ENGIN 1N33BG COMFORTILT STEERING 1RP5AC 875 X 165 X 6 TIRES 1U63AF AM PUSHBUTTON RADIO 1Z84BZ CUSTOM SPORT TRUCK 1621AE SADDLE VINYL CUSTOM RIGHT SIDE: 1A11AA TINTED GLASS 1C60CF 4-SEASON AIR CONDIT 1F59AA FRONT STABILIZER 1G60AB AUXILIARY SPRING 1M49AJ TURBO HYDRA-MATIC 1N40AG POWER STEERING 1RP6AC 875 X 165 X 8 TIRES 1Z53AC AMETER-OIL-TEMP GA 1464AA YELLOW/WHITE/L I am assumeing that the reason the tires are listed twice is that its been up graded to 8 lug? I am also guessing that the helper springs under it are factory, the aux spring? The truck has 81,789 miles on it. The truck is very straight and solid. I have only found one spot on the bottom front R fender thats through. I spent the afternoon cleaning out the garage so I could get around it. I have not had time to go through the bed or cab. I want to paint it back to the factory yellow and white. Im going to keep it mostly stock with a few changes. The other truck in the pics is my 1971 c10. Its mostly all orignal with just over 100K on it. Its very base with only a couple options. I will be getting rid of that one sometime due to lack of space to keep all my toys. Any help would be great. Thanks. Joe

Re: What is it? C20
3/4 ton trucks are 8 lug from the factory. The SPID reads 396 cause that's what the guy typing them that day put on it.... if it is a 71, it has the 402 (which is a 396 punched 030 over)

Re: What is it? C20
The second tire listing is the optional spare.It says Custom Sport Truck,but it`s a Cheyenne.It says 396,but it`s a 402.That`s typical for`71.

Re: What is it? C20
its interesting that it has the Eaton rear in a big block truck with no optional gear listing. Big block/auto c/20 trucks supposedly got the dana with 3.54 gearing.

Re: What is it? C20
I noticed that too....I thought the Eaton was only used up until 70, and the Dana 60 was used in 71-72?

Re: What is it? C20
71swb4x4 - Going mostly stock. Would like to add a tach dash and wood bed. Maybe a set of '02 HD wheels. Although the hubcaps are growing on me.
I have no Idea on the rear. The production date is 1/71 would that have anything to do with it?

Re: What is it? C20
I have heard the Eaton is stronger (although I have never seen a dana 60 break) but they are very hard to find parts for.

Re: What is it? C20
Hmm... never heard anything bad about a dana either. parts as far as seals and such or parts like gears are hard to find? Thought about changing the ratio to a more highway friendly ratio, as I would like to drive it alot, and going with an overdrive trans. I dont do much pulling, and that BB has pleanty of torque.

Re: What is it? C20
Thanks for the clarification on the Eatons. I have had several CJ rock crawlers with dana 60 rear ends and no problems with the axle shafts. In fact, they are a very popular swap with Jeep dudes. The AMC 20 (used from 76-86) has to have the weakest axle shafts ever built...I have seen plenty of those break, and have broke a couple myself.

Re: What is it? C20
I think the 6 and 8 with the tires refers to the ply rating. The G60 aux spring is the long leaf spring between the frame and the coil spring mount on the H052 axle tubes. More parts are becoming available from NAPA for these trucks like vacuum boosters and rear seals.

Re: What is it? C20
Here are the trucks Ive owned. The first is a 72 4x4 short bed step side with a 350 and 4spd, 35x12.50 bfg's, 1 ton axles and custom springs. The second one I bought is the yellow 71 c10 307 th350, 95% orignal/stock. The third is a 72 Cheyenne Super. I still have the 71, but did not have room at the time to keep either of the other two, due to moving and such. The blue one was beat, not a straight pannel on it. The Super was rusted out.

Re: What is it? C20
if the HO52 has the 4.10 gear.....extremely likely due to the big block.....all you need is an overdrive trans to make it a highway driver. a 4l80 or better an allison 5 or 6 speed would be awesome in that truck. if you have a more conservative budget, you can build up a 200-4r or 700-r4 to handle a mild big block no problem. heck, if you geta used one in good condition it will last a long time provided you run good fluid (synthetic atf) and don't beat on it.
