Nice looking truck. The 6-110 is pretty rare.

Nice looking MH's above by the way.

If you didn't see a red truck, you might question your truck photo history.

Side note the green and yellow long hood posted look similar to the one I posted above.

I was wandering around Flickr & found this 7-Up delivery truck. Rather new considering it's a Topkick.

I liked those with the Cat 3208T. No fun to work on but smooth and quiet with a great turning radius.

Did you see that one has the same paint as the one shown earlier? Must be original, which I questioned on the first one.

Not one of the newest Top Kicks, though. I always liked those soda and beer haulers, mini tractor-trailers

That's a good looking Chevy

Bob, did any Top Kicks ever get a 2-Stroke Detroit?

As usual, my knowledge doesn't go much passed '76, lol.

GMC wasn't the only one with this interesting concept, White Trucks called it a "giesel". This was a 470 cu in gas V8. One premium feature that the White engine had and the GMC gas engines did not have, was the "wet sleeve"

Sadly no. The vast majority had Cat 3208's, and a few had Detroit 8.2T's. A very few had Cummins VT-225's, that was discussed here some years ago.

That there was an idea that didn't pan out! The 'Giesel', sometimes called the 'Mustang VIII', was a small Cummins V-8 diesel modified to run on gasoline. It had lower compression pistons, spark plugs in the injector holes, and a Holley 2 bbl. carburetor. Needless to say it wasn't very efficient and sales were very low. I don't know if the engines were manufactured by Cummins or White. The Giesel was only around for a year or two.

Doesn't seem to make much sense from the get-go. What made them think going back to gas was a good idea?

A lot of work went into that one. Reminds me have any of you ever seen a sleeper cab on a Steel Tilt? From what I can find out, they were not exactly 'factory', though they are shown in a few sales brochures. There were at least 2 companies converting them and they could be ordered from the dealer (truck was delivered to the body company after manufacture). Most were steel construction and looked very 'factory' but some were a fiberglass cap like the sleeper on a Ford C series.

Found a picture of the steel one:

The improved version was the Toro-Flow 11. This article shows what was done for durability over previous versions. Maybe too little, too late?

Possibly, but the new head gaskets and revised max R.P.M. governor setting addressed 2 issues the engine had. The Toroflow certainly had it's share of problems but so did most of the competitive mid-range diesels of that time, like the small Cummins V-6 and V-8's, the Ford Dagenham and Dorset, and the Internationals. In fact about the only reliable mid-range diesels back the 60's were the Detroit 53 series engines. A lot of the problems were caused by operator error. Engine overspeeding, poor quality fuel, improper maintenance, and overloading. Overloading was also caused in part by dealers, who would spec. trucks with a Toroflow to win fleet bids. Toroflow diesels were inexpensive compared to a lot of heavy duty diesels but equaled many larger diesels in H.P. and torque. Around the time the Toroflow II came out the engine was also dropped from the higher GVW trucks. Eventually the 220 H.P. DH 637 V-8 Toroflow was discontinued as well.
