Just can't get a good basic truck, like the old days!

GMC also had a V12 gas engine which was 2 V6 blocks molded together. It had two carbs, two distributors.

most 70’s-90’s diesel vocational trucks were underpowered EMPTY.
210HP was the normal power rating for a 33,000LB dump truck.
That’s absurd.

It’s still hard to find single axel trucks with any power. Ford has been putting 6.7s in 650s and 750s for the last 10 years or so but before that they were using 5.9s or 3116 cats. The 6.7 is better but it’s still underpowered if you actually want to use a 750 to do 750 things. The vast majority of those are fleet trucks and I think they’re under powered on purpose to save fuel and keep drivers going slower. Ford is still building medium duty trucks with gas engines.

GM/Detroit did all kinds of variation on the diesels too. The 71 series ranged from one, two, three, four and six cylinders, and the V-types six, eight, twelve, sixteen, and twenty-four cylinders. The 92 series ran v-6 to v-16. Other series had a number of variations based on common parts too.

They also made reverse rotation versions of some engines

We had a GMC Topkick 3000 gallon water tender(Tender not Tanker ) with 8V92T at our fire station. That thing was LOUD during pump operations. I van only imagine the 16V92 at rated RPM; must be an amazing cacophony of sound!

Lol, ask for a Tanker and you get a plane, right?

Nice shot.

On the East Coast, if you ask for a tender you get chicken!

Yes, there are some differences in nomenclature West Coast vs Midwest vs East Coast. But when things hit the fan, the job gets done !

Yup, 702 CI, (2) 351's.

Anyone remember these jewels? We had a '65 KW with a log loader on it and 7" muffler/stack, it would stand some fire. Original output was 275 but someone put a 320 pump on it before we bought it. It was cool as hell. Then we had '60 Pete with a 9" muffler/stack and it wouldn't do it. It was 290.

Your assertion of “underpowered” is due to 2 reasons
1. The engine’s rating. Most companies buy lower powered/smaller displacement diesel engines in their trucks to save money. The more underpowered, the less “cowboying” the truck gets
2. The engine’s displacement. A 6.7L Cummins is an excellent engine. However, it doesn’t have the rotating mass to get the load moving and keep it moving like a larger displacement diesel.

Anyone remember GM “Toroflow” diesels?
Way before my time, but my grandpa, who owned a fleet of fuel delivery trucks, used to tell me about them.
