Here's something else I'm fairly sure about: The 1970 rear end housings were wider and the axles longer.

And I'm wondering if the 70 models had sealed gas tanks with evaporative emissions canisters.

I'd like to get my hands on that setup to get rid of the vented cap and gasoline smell in my garage.

That was a mid year thing so many were, but some were not. I have been meaning to measure mine.

I've owned a 67,68 ,69 ,three 71s and three 72s .

Never owned a 70

**MikeB** · 08-24-2022, 05:06 AM

With stock wheels, the rear track on my 69 was so narrow that 235-75 tires were very close to the bed. In fact, the bed had a tire rub mark on one side! That's when I remember reading (back in the early 90s) that 1970-72 models had wider axles.

I ended up installing 8" rally wheels which moved the tires outboard at least an inch, which gave even 255-70s more bed clearance than 235-75s. At that time I also had a race car shop re-drill my axles for 5 on 5 because 71-72 axles were too long. The shop also had to turn down the pilot on the axles by a small amount so the 5-lug drums would fit. So my 69 axles have been Frankensteins for almost 30 years!

**special-K** · 08-25-2022, 07:15 AM

I get people asking, "What year is that, about a '76-'77?" when I'm getting gas in my '72. I thought everyone in the whole wide world knew the body changed in '73, then squarebodies forever

Lol just this morning I had someone calling my 67 a 77

**MikeB** · 08-25-2022, 10:50 AM

I get people asking if my 69 is a 71 or 72, but I don't remember anything farther off-base that that.

When I had a 55 Chevy car, a older guy in a parking lot said something like, "Nice 56." When I told him it was a 55 he said he was pretty sure it was a 56 because he had one when he was younger. I just know he walked away thinking he was right!

I'm an older guy now and sometimes think I remember things like places and date, until my wife corrects me! However, one thing I never get wrong is the years and models of old cars and trucks, even the Oldsmobiles and Pontiacs my parents had in the 50s to 80s.

**71CHEVYSHORTBED402** · 08-31-2022, 10:05 PM

Chevy guy at the local gym drives a 70, he's had it forever. The guy's as old as I am, on our last 1/4, or 1/3ish with good blessings. He had trouble believing the 400 is a 402 instead of a 400 SBC.

These trucks are an education. Even vendors and experts got it wrong on occasion, sometimes must be doesn't apply to any.

OT: On occasion my girlfriend sent me pics of square bodies, "look, a truck like yours"

May as well be, she's a California EV girl

Guess what a car show means to Sacramento? No Chevy trucks short a Luv, 2% interesting and 98% new muscle, sport and EV cars - Neat.

**MikeB** · 09-01-2022, 01:27 PM

I'd have to look this up. The 396 became a 402, but was still called a 396 by GM, right? Or was it called both?

**Steeveedee** · 09-01-2022, 02:07 PM

In '69 it was called a 396. That held true for '70 except for trucks and the big cars, which if my memory serves me correctly, got 400 badges, and I think that the SBC 400 was available a well as the BBC 402. It was a few years later that the SBC 400 was available in trucks. I worked at a couple different dealerships back in those days, but I could have it slightly wrong. This is from memory.

**MikeB** · 09-01-2022, 02:52 PM

Steeveedee, I'm diggin' your old skool camper setup.

**Steeveedee** · 09-01-2022, 03:45 PM

Thanks! That shell is about 6 years old. The wife went with these side windows, but the really old school aluminum frames were still available.

Here's a bigger pic. This is not a '72 Chevy, either!

Just a nod to the thread title.

If I am correct our trucks were never available with a small block 400.. I will let others chime in ..

**MikeB** · 09-02-2022, 12:17 AM

For 1970, the GM Heritage Center shows the 250 and 307 as standard, with 292, 350, and 396 as options, but no 400.

The 396 was also available with a couple different 4-speed transmissions. One was called "close ratio". Both came with a Dana 3.54 rear axle.

Now those would have been some cool trucks!

That's interesting. Check out page #13 of this document entitled:

C-K10 Series -- Gasoline
Options & Accessories when Installed by Chevrolet

https://www.gmheritagecenter.com/doc...olet-Truck.pdf

No listing for a 402 as an option.

So, Chevy called the 402 a 396 in the specifications but a 400 on the emblem. And then to confuse things further, they put a 400 emblem on 70-76 full-size cars with an SBC 400.

Beautiful truck you have there.

Thats about it

My SPID is listed as a 396, not 402.

**Steeveedee** · 09-02-2022, 04:59 PM

My '70 Chevy SPID says L47 400 Cu. In. Look how they spelled Turbo Hydra-Matuc

**michael bustamante** · 09-02-2022, 07:04 PM

whatre you talking about, it looks like a 72 to me... lol

Funny. A 402 is shown as a 396 on the SPID and a 400 on the fender emblem.

Apparently there was some "rounding" done at various departments at Chevrolet Motor Division.

My 69 had a 307, and I got no emblem.

**Steeveedee** · 09-02-2022, 11:43 PM

I guess that they don't "brag" about the standard engines?
