I stand corrected. The '58 and '59's looked factory to me, but I now see factory 4 X 4's didn't start till '60 as you have stated.

Starting in ‘57, you could get a truck new from the dealership with the NAPCO conversion. (It didn’t leave the factory as a 4x4).

Another of the jimmy fuel tanker

I sure like those lo-pro tankers. That Cannonball needs a chop top and lowered on airbags .

I bet it was warranty costs that halted the turbos. I just looked at a YouTube video that was a '62 Olds ad for the new Jetfire. That car was a leap forward. They didn't talk about the rear transaxle/independent suspension. It was all about that 215 aluminum V8 with turbocharger that put out 1hp per cubic inch. They put three years into development. but one thing different was they had a fluid you added under the hood, which I imagine either helped cool or lubricate, or both. And I bet buyers didn't keep up on that. We didn't see turbos used for a long time after those.

I think only the Pontiac Tempest version had the transaxle/IFS, the Olds F85 and Buick Special had a regular rear axle with coil springs.

Yeah, didn't see turbos on cars for some time after that one!

That body was used for a lot of firsts. I get them confused between makes. There is one with a transaxle rolled up on it's side, for decades, at this abandoned property not far from me. I thought I remembered it was an Olds. I remembered wrong

Now for a crowned jewel of a GMC. It leaves me struck in total awe.

Put a bunch of miles on this 1981 C70 back in the day. 8.2 Detroit turbo and a 5 speed Allison automatic. Not exactly a powerhouse, lol. Doesn't look this nice anymore, unfortunately. Trying to decide what to do with it.

Handsome tandem

I think this one is a '66

Factory stock
Not so stock
And a great hay hauler

Here’s two I got a few years ago. A 1965 gmc 5000 (not sure) with a toro flo diesel and a 1964 gmc b7000 twin stick winch truck. Both have been in the family for a long time.

[C10 - C90 Bill]

The '65 is most likely a 5000. They didn't put a Toro-Flow in a 6500.

Cool trucks.

What does the 7000 have for an Engine?

[special-K]

Is that straight pipes on the Toroflow? What does that sound like?

And welcome to the board! You have a couple cool GMCs

[Winchrig]

The 7000 has a Detroit 6-71 and the toro flo is not straight piped.

[Winchrig]

My cousin was dragging the 7000 around and it accidentally pull started and hit the loader, it sheared a piece right off the pipe bumper and wrecked the passenger side fender and hood.

Reminds me of my friend's '69 Mack R-700. He bent the front bumper and got the loader out to try to straighten it. Out of a strange co-incidence, he left the truck parked in Reverse. The 8V-71 fired up and started moving backwards. Luckily the trailer brakes were still holding and it finally stalled out. He would have had a lot more trouble than a bent bumper!!

[Winchrig]

Wow, he got pretty lucky. I will post a video of the toro flo next time I get it going.

I have seen Toroflow trucks with dual stacks but horizontal mufflers under the frame. C series and tilts. Must have been an option.

[special-K]

I wondered if that's what it had. I don't think I'd want to show off a Toroflo by running straight pipes.

These stories of self-starting diesels are interesting.

[Winchrig]

That’s what this one has, the horizontal mufflers in the frame.

[C10 - C90 Bill]

I would love to hear one with Straight Pipes, lol.

Speaking of loud, my 478 had what I believe were factory type straight thru's. Duals, of course. One day the pipe broke open before one of the mufflers. I can just imagine it with straights, lol.

[special-K]

I'd like to hear it, but wouldn't want to be running it that way very long

I'd like to see a picture of that Toroflow emblem up close. That's a rare item right there

Has this one been shown yet?

[C10 - C90 Bill]

That truck sure is a beauty. A '64 and if it has a 409, it would be a C-80.

Here are some pictures of Emblems from Jolly's site, including the Toro Flow:

My '67 7500 with the 6V-53 still had the Toro Flow Emblems on the butterfly hood. It was what it once had before it got converted.

[factorystock]

Great looking '64 tractor, thanks for sharing special-K. IMO, these Chevies look best when they are correctly painted, especially the front end, as this one is. Hard to say if it's an 80 or a 60H model, these trucks require close photos of the emblems to tell. The Toro Flo is quite an engine, GM attempt to get a diesel to the medium duty market without a premium price tag.

[C10 - C90 Bill]

As much as I like the Toro Flow, it did not have the best record. Most owners had complaints about them, right down to some saying they should never have been converted from the gas engine. Same with my '67. As nice as the truck was, by the time I got it, it was long gone. I sure didn't mind the 6V-53 that replaced it though.
