66 Chevy truck listed in an on-line auction

SDE · Aug 2, 2014

It is listed as a Chevy 10. It is a 4 wheel drive with a plow. They show 8 bolt rims. What size are the tires? And is it a 3/4 ton or is it a 1/2 ton? I thought the 8 bolt rims would be a 3/4 ton. Did the 3/4 come with 16 in tires? Whoever took the pictures showed the thread but not the sidewall of the tires.
Thank you

The Chevy 10 is a 1/2 ton. I think 6 bolt wheels were still being used in '66. 15 inch tires were standard, 16 inch was optional, but a lot of them DID have the 16 inch tires.

The Chevy 20 was the 3/4 ton version, and probably did have 8 bolt wheels with 16 inch tires. 4 wheel drive in '66 was fairly rare. The 4 wheel drive craze didn't really catch on until the mid '70s.

I would expect a '66 to have 16" rims. However a 16.5- 8 bolt will fit right on so who's to say they were not swapped in the past...

Ultradog MN · Aug 2, 2014

I'm pretty sure 8 bolt would mean it's a 3/4 ton.
1/2 ton 4x4 would have 6 bolts and a 1/2 2wd would only have 5.
Badges could easily have been changed.

ypop · Aug 2, 2014

could have been converted to 4X4 using a 3/4 ton truck drive train. or replace the hood with one from a half ton and left the badge on saying its a 10. Hard to tell from pictures!

Eight bolt wheels sounds like a 3/4 ton axle.

In the 1960's 4WD pickups were not as common as in the 1970's and later. In the 1980's it was popular to mount different bodies on 4WD chassis, creating 4WD El Caminoes, 4WD Camaroes, 4WD Corvettes, etc. Could someone have swapped axles, bodies or chassis on that pickup?

Snow plows can be very hard on a truck.

Sorry Ypop, we must have been typing at the same time.

looks like we were LOL not a problem ss55

How can a person identify what the drive train might be? I was thinking of buying it just for plowing the driveways. Or I could put the plow on my truck.
Have welder---can cobble anything together.

somethins up, either the truck is mis identified by its owner, its had the hood replaced as mentioned or its a built truck from 3/4 ton componets the reason i say that is i had a neighbor now deceased who bought a 66 chevy k10 4x4 brand new he had it untill he died and his son still has the truck, it always had 6 lug wheels on it if you can acess that truck you can do some detective work, look for the vin number on the left front frame rail and see if it matches the number on the cab if so the unit is complete and is either a original 3/4 ton or has had 3/4 ton axles put on a half ton frame,not unusual for plow duty , and its actually a good swap, if it doesnt match then you have a c-10 sitting on a frame from something else then its time to look it over and make sure the build was done well and not a cobble job , for example there was one guy around here back in the 1980's had built a 73 or 74 half ton 2wd suburban into a 4x4 but... its running gear was 3/4 ton ford! this rig was a mess! anything over 40 mph and it took 2 lanes to keep this thing headed in the same direction, not what you want

5 bolt 1/2 ton, 8 bolt 3/4 ton.

David G · Aug 2, 2014

3/4 ton would have had 16 or 16.5 rims, I am not sure on the 1/2 ton.

JMOR · Aug 2, 2014

Not to jump anyone's case, but just because you have seen one or some does not mean it is universal or applies to all. I own a 1962 C10 (1/2T) Chevy, bought new & never modified in any way, except paint color, and it has and has always had 6 lugs on 5 1/2 center.

David G · Aug 2, 2014

Might be right, just sure it is not 8 bolt.

old popper · Aug 2, 2014

That vintage Chevy would be ...1/2 T 6 bolt, 3/4 T 8 bolt.

ss55 · Aug 2, 2014

You could also get 17.5 wheels and tires on 1966 Chevy pickups. They were not a common size.

Dad had a '66 Chevy 3/4 ton with 7 x 17.5 6 ply Firestone tires on split rim wheels. They were way undersize for the 7500 GVW of the pickup so about every year one of the rears would get a sidewall bubble. The tires had a pro-rated warranty, so he had to replace them with the same. Our regular garage handled Goodyear. After a while the Firestone dealer knew the drill when dad's pickup pulled in.

Okay Chevy speak from the 60's 10=1/2 ton, 20=3/4 ton, 30=1 ton C=2wd, K=4wd
A '66 "10" should have 6 bolt rims, the 20's and 30's would be 8 bolt. At some time in the 70's they made things more complex where the C10s had 5 bolt rims and the K10s had 6 bolt rims, 20's and 30's keep 8 bolt

A 66 Chevy is now 48 years old, if it has a plow on it that means it lives somewhere that has snow which usually indicates that trucks from that area usually have RUST, and trucks from the 60's used to be pretty good at rusting out. What I'm trying to say is we're telling you what it was/should of been from the factory but a lot of time has passed since this thing was at the factory and in the ensuing years a lot has happened. It is more than likely a few parts have been changed. It is more than likely the person installing these parts was more worried about "will this fit" or "this fits and it's cheap" then what was correct or factory. As others have hinted it might be more of a collection of parts made up to look like a 66 Chevy then being an actual 66 Chevy.

Factory '66 1/2 ton Chevy 4X4 has 6 lug wheels. My nephew has one & it's a 6 cyl,3 on the tree short,step side

2x4 · Aug 2, 2014

8 BOLT RIMS WOULD TAKE LT245R75-16 tires

ericlb · Aug 2, 2014

after this amount of time, being chevy, the drive train can be virtually any chevy engine, i may be wrong but i think the mid 60's chevy4x4 had a divorced transfer case, so after 63,when the inline 6 cylinder went to side mounts instead of 1 on the front and 2 on each side of the bell housing, any engine or transmission can be bolted in just by swapping mounts, and adjusting the driveshaft if it was a original v-8 it may be a 283 or 327, the cars got the 327 first im not sure what year the trucks got it, but its right about there somewhere , by now it could be still original or clear up to a 454 big block, it will basicly bolt right in there. from '66 its almost sure to have picked up at least 1 engine somewhere, unless its one of those that only plowed snow and was parked when it didnt

Tx Jim · Aug 2, 2014

(quoted from post at 17:53:54 08/02/14) if it was a original v-8 it may be a 283 or 327, the cars got the 327 first im not sure what year the trucks got it, but its right about there somewhere ,

I bought a new '66 1/2 ton Chevy PU with a 327/4 barrel carb. Engine was a 4 bolt main brg, 8:1 compression truck engine that would really pull good.

Sidekick · Aug 2, 2014

I have an original '66 C10 sitting in my driveway. 6 lug wheels. For engines they mostly came with a straight 6 and if a v-8 either a 283 or 327. Transmissions could be almost anything. 3 on the tree, 4 on the floor or in my case a Powerglide.
