Re: GM Semis
A Gas Engine in a Long Nose? Wondering if that was really available. I've never heard of one. Possibly in the early days of '66 or '67? If so, I'm sure it was the 637 V-8 only.

Re: GM Semis
Yes and yes! I have never seen one or even a picture of one though, but that model is listed in the Data Book and brouchers. There were a very few 637 gas powered Crackerbox cabovers made, a guy on the ATHS website had one years ago.

Re: GM Semis
Bob, Just as an update, how many 9500 Conventionals have you ever seen with a 637 V-8 Gas?
Also have you ever seen one yet with a 10-Speed Road Ranger behind it? It's been just about 50 years now since the company I worked for took delivery on a JE with a 10-Speed and in all those years, I have never yet to even hear of another. I have also researched it pretty thoroughly through the years. Did we have the only one in the US, lol?

Re: GM Semis
Just a couple and they were HE series fire engines. Seems that mose 637's came with large Spicer 5 speeds but the consensus seems to have been they needed more gears. A 10 speed or 5X4 would probably have ideal.

Which reminds me of the '68 Long Nose I saw a few years back. It had a 6-71 instead of an 8V-71 but to my surprise, it had a 5 and 2 (2-Speed Rear). I had never seen one in a Long Nose before but sure enough, it was a former Firetruck.

Re: GM Semis
Another beauty from Pacarhauler! Looks like a 62 Biscayne behind the cab.

Re: GM Semis
That's what I was thinking. Probably lowest production numbers on the load.
Where that 4x4 factory in 62 or a conversion. My pre 73 history is lacking.

Re: GM Semis
Starting for the ‘60 model year, GM did the 4x4 in house on the 1/2 and 3/4 ton trucks.
Prior to ‘60 it was a NAPCO conversion. It was also a NAPCO conversion on the 1 ton and heavier trucks from ‘60 until??? GMs first in house 1 ton 4x4 was 1977.

Re: GM Semis
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.

Re: GM Semis
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).

Re: GM Semis
GMC offered the 6-71T early on in the 970 series around 1957 rated at 235 H.P., when most 6-71's were 180 H.P.. They must have dropped the engine option sometime before 1960 because I can't find any records of it after. I don't think the 6-71T returned to GMC's until the early 80's.

Re: GM Semis
That does sound familiar. I believe I read some details about that somewhere.

Re: GM Semis
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.
