67-72 C/K/T-40's-90's! - Page 30 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Bob, I have located some 637's online with 2 sticks. A town in NY had some. The 637 and the 10-Speed RR was a good combination. With a full load (30,000) it would die on some hills like a Detroit and require a lot of shifting, which I didn't mind, but was pretty impressive none-the-less. I always wished they gave me a Detroit though, lol.

Here are a couple we use around the farm. The 72, 366, 5+2 has been there since it was new. The white 70 350, 4+2 is handy for hauling out of the field, but it has made several trips to the elevator. Just have to be extra mindful in the curves!

**special-K** · 02-09-2022, 10:16 AM

I love seeing that you work these trucks. I see a few in use on farms around here, grain bodies. I think that's just great.

I don't know if I've showed these yet. But I keep finding them on Purplewave.com. I hope one can wait for me before they all get cycled out. One day I hope to raise crop on the family place up home in the mountains. Not a lot of land, but could offer my services around the county, just to enjoy putting one to use. I guess I could do that here for now

Heavy Mediums are cool trucks.

I'm on a weekend trip with my wife & I swear I've seen 3 67-72 C50s or larger trucks. Scavenger hunt in western NC.

crazyjeenyus · 09-03-2022, 12:15 AM

Just picked up this beautiful '67 C50. It was sitting in a field less than 5min. from my house. And yes that is a Radioshack speaker mounted in the corner -gives a whole new meaning to the term head-banger

C10 - C90 Bill · 09-03-2022, 08:42 AM

Looks good. Keep us posted on it.

**special-K** · 09-04-2022, 08:43 AM

Looks like a good one! Radio Shack, that would be Realistic, right?

Cool truck, interesting story, great work on the wheels. But you could probably guess what I'm going to say, lol. Too bad it's an Automatic.

Truck also sounds great and pretty surprising fuel mileage. My 478 Gas would only get about 7-9 MPG.

While I know the Chevy H/J90s and GMC H/J9500s (and their respective Bruin and Brigadier equivalents from 1978) could have the Detroit Diesel inline 6-71 engine with either hood style, I think that if these were ordered with the turbocharged inline 6-71T then they would need the fiberglass tilt hood on it, in order to clear the turbo, correct?

**Bob B.** · 03-07-2025, 03:50 AM

I think the only diesel available in a 90/9500 series with the steel 'butterfly' hood was the 6-71. You would need to find a data book from '78, '79, or '80 to find out for sure as the first year for the 6-71T in those trucks was 1978. The last year the steel side opening hood and fenders were available was 1980.

Yep, 1978 was indeed the first year for the turbo inline 6-71T as well as the low-RPM 6V-92TT "Fuel Squeezer" and the Cummins Formula 290 in these. It's even mentioned in a trade brochure titled "BRUIN - CHEVY'S NEW PAPA BEAR."

Yes, I have a 1977 data book and only the 6-71 is listed for the H/J series. You are probably right, the 6-71T was only available with the 'Brigadier' hood.

I had no clue of the pecking order of those trans!? I always though top dog for toughness was the 420 out of those three.

The 420 just has the lowest 1st gear ratio (ever) at 7.05:1

I take it you disagree. If you think that one looks good you probably even think these do
