I can remember when I was a kid the 348, then the 409, was just an awesome engine to me. Have read somewhere that the motor was actually designed as a truck engine, GM got behind in the big block power race and rigged it up in the cars. But I spent several years working is gas stations back in the day and I've never seen a W motor in a truck, ever.

Was the 348 ever actually put in trucks? The 409? Seems like that would make it much more plentiful, which it never seemed to be.

348/409 where in larger trucks and not available in pick-ups. Many people say the w motor is a truck motor but I think it was designed also for the cars as the cars got larger and a little heavier after 1957.

There were a lot of 409s used in industrial applications.
I grew up on a farm in the Texas Panhandle. Most of the farms there are irrigated, and back then there were a lot of 409s put on irrigation wells. I know where there are about 15 of them sitting in a pile behind one farmer's barn. He had them rebuilt so many times they couldn't be rebuilt economically. It was cheaper to buy another engine.
By then, the Chrysler 413 industrial engine took over the local market. It was R.I.P. 409.

Whoa, a 409 running a pump. Probably a pretty severe duty service actually and really racking up hours.

Not a pickup powerplant either, that explains that.

Thanks for the info.

There are many reasons to appreciate the 348 & 409 engines. I think alot of people have a fascination to see them at cruise- ins and car shows because of their history and also the Beach Boys song about them that everyone has heard, that tune and the catchy phases stay with you a long time.
People want to know what is packed under the unique valve covers. When a W engine vehicle shows up somewhere a crowd always forms around it.
And they are super exciting to drive around in.

To answer the original question, NO, the 348 was NOT specifically designed as a truck engine and then installed in cars. NO, not so!
That is a VERY, VERY old wives tale that has just continued to pop up occasionally.

This is part of a chapter I wrote for a publication that hasn't been published yet, so it is copywrited.

"The project was handed down in 1955 (yes, just when the new 265 made its debut) to a team of engineers. They were John Rausch, Howard Kehrl and Donald McPherson. Upper management handed them a short list of objectives to be met by the new design:

1. Adaptability to a broad range of displacements with a minimum number of different parts
2. Adaptability to broad compression ratio change
3. Dimensions compatible with the anticipated space limitations of passenger car design
4. Provision for mounting both passenger car and truck accessories.
5. Flexibility of machine tools to accommodate future engine modifications

It is very clear that the above objectives did not involve a design for a new truck engine that was “later” adapted to passenger cars (as magazine articles have stated since ’61 to the present, with the same regurgitated folklore). The engine was designed for both uses right from the beginning. Design objectives #2 and #5 especially seem to be created for the (then unknown) future hi-performance developments that were to follow."

notcamero,
These engines were run on natural gas, so they ran very clean.
The average season was 9 months of running. 24/7. They were pulling a 6" pump at a depth of around 3-400 feet. Zero vacuum, w.o.t for 24/7. During a 9 month season that runs over 350,000 miles per year.
I knew one engine that ran for 7 years with out anything but a valve job.

When we pulled it down for low oil pressure. It was as clean as it was the day it came out of the factory. We honed it, put new cam bearings, new rings and lower end bearings and let it eat.
We didn't even bore it. Virtually no ring ridge.

I loved those engines.

OK Verne, what's the latest on the book? Do I need to reserve one, or 2, or 3?

Don't know about that copywrite, but sure sounds like an interesting book. Keep us posted on that!

The 348 engine replaced the 322 Buick enine that was used in lager trucks in 1956 and 1957. The 348 was detuned for truck use and developed less horse power than the car engine as it was set up for low speed torque and regular grade gas.

Gene,
There was no Chevy 348 engine in '56 or '57 models.

Perhaps I did not word it correctly

In 1956 and 1957 the larger displacement engine for heavy duty trucks was the Buick 322 . In 1958 the 348 was used for heavy duty trucks with the 322 still used in school buses.

Also, at one time back then, there was an Oldsmobile V8 used in trucks. What years and displacement Olds engine was used?
