The Diffference between the 67-72 Chevy Trucks (Table Version)

[LSUMurse]

I put this together from this thread: http://67-72chevytrucks.com/vboard/s...d.php?t=323797 from which most things were cut and pasted.

I am attempting to make a table that will give a somewhat easy reference for the differences between the truck years. In doing this I have learned that there is almost as much uncertainty as there is fact. I would like this to become an ongoing database that people add to. If someone offers something new in a reply and someone can confirm it, I'll go back and edit the table. If someone has a suggestion to make it easier to read or organize, please let me know. Thanks to GOPAPA who put the first thread together and to those that contributed to that one.

---------------------------------------

For those of you who are learning about these trucks, it's fairly easy to tell what year they are. The six years of production, from 1967 to 1972, are divided up into three groups of two years. We have the '67-'68 trucks, the '69-'70s and the '71-72s.

Thanks to any and all who contribute, even if just to ask a question. Most of the hyperlinks to pics will be from this website, that I have saved to my Imgur account. Thanks to those whose pictures I have used, even if you don't know it.

Disclaimer: This is not intended to be perfect. I don't believe it will ever be 100% accurate as a lot of the information to confirm things is lost.

[LSUMurse]

That got a lot larger than I thought it would be. Maybe it's not easier to read. Let me know if this is just a wasted effort.

[Bigdav160]

Power windows in '72. I've never seen one.

[LSUMurse]

Someone questioned that in the other thread. Removed.

[67 cst swb]

I believe that my 67 CST 1/2 ton came factory with a 327cid and a TH400 transmission.
I don't see that as an option for 67.
Great job on the list. I never really knew how to tell the 69's from the 70's before.

Thank you for posting this table.

[68blazer]

i don't know why i was thinking you would show the differences in sheetmetal pics (kinda like an LMC). Then again i guess i could look at an LMC.

still a good thread

[OSM 70 C20]

Is there a 350ci V6?

[JointTech]

good info. just breaking your balls here but that isnt a table.
needs Pics to really make it useful. A lot of that stuff only helps if you know what you are talking about.
ie what is a 67 style ignition bezel?

I'm learning a lot just by doing this and honestly I have no idea myself. I just put it together from the other thread. I'll take my laptop to work with me tonight and see if I can't create hyperlinks with pics for most of the differences. Work computers are protected by Barracuda, a royal pain in the rump.

67 bezel now has a hyperlink to a pic.

Title changed.

Thanks. It did end up being a little more than I thought it was going to be. You've been here a while. Please make suggestions or additions if you have any. My biggest concern is disinformation. I'm going to do my best but the community can be a big help.

In looking around the net, GMC made a 305 and a 351 V6. Now I have to figure out if it was a 305 typo, or truely a 351.

[yote1234]

Engine options: 250ci and 292ci I6, 307ci , 350ci, and 402ci V8(called 400)

Cool table. Just a few notes. I have a '67 K/10 Suburban, it has a slide ashtray [which is not compatable with the slide ashtray in my '71 GMC Jimmy K/1500 4x4 ''Custom''.] My '68 C/10 Stepside has the ball-bearing ashtray -- called the "Deluxe Ashtray" on the build sheet, which has since disintegrated and lost itself, but not mentioned on the SPID.
Also GM for whatever reason refered to inline engines as "L6s'' back in the day, not 'I6s' which Ford uses. Now GM calls them I6s too, but if you want pure historical accuracy, say "Ell Six." The Iron Duke 152 CuIn was an L4, but not a truck option in the '67 - '72 period.

Yep 305 and 351 V6's. I think 69 or 70 was the last year you could get either in a pickup though.

[OSM 70 C20]

WOW! Cool!!! (I didn't mean to distract from the tome of the thread).

It's got a smaller diameter on the surround and no ACC function.

[franken]

I like the idea but the multiple colors are (to me) a negative to taking it seriously.
Deciding how to present the info is difficult.
I would look at a relaxed standard US book style format and use that until a better idea came along.
I'd also use USA capitalization rules. Capitalize the first letter of a sentence, proper nouns, and not much else. Basically, when in doubt, don't. Same with commas.

Check the ashtray hyperlinks and let me know if they look like yours, please.

Yeah, initially the I put the colors to try to make it easy to go from one year's subcategory to another to see if there were differences, but it does look a little amateur.

As far as the capitals and such, I do a lot of start and stop typing and adding things to one spot and going to another, so that'll explain a lot of the punctuation errors. I do plan on proof reading it in 16 years when I finally finish it. Punctuation is a lost art.

[LSUMurse]

1969 GM Heritage website information kit only lists 250/292 six cylinders and 307/350/396 V8's. There is no mention of a 327. Can anyone verify yes or no?

Do you know what years TH350 and 400's were offered? All the RPO's etc just list "Turbo Hydra-matic" with no other designation.

By "special air vent handles" are you referring to the ones down in the kick panels?
