Have you ever wondered why your truck diesel is a straight six?

Most straight sixes besides a few odd balls were goiod engines, once they got away from babbit bearings, but the 300 six (probably the best) and the 225 slant six was used in a lot of industrial applications too, because of their reliability and they way they lasted forever.

 

DynaFlow was Buick only

From 1940 to 1955 Olds used the 4 speed HydraMatic, not to be confused with the later GM practice of calling everything Hydramatic. IMHO this was one of the best 4speeds GM produced until they moved to electronic control. The original HydraMatic didn't have park and had two pumps with one that would allow you to push start the car. This was the 4 speed transmission in Olds, Pontiac, and Cadillac, It was also used by Nash, Lincoln and Hudson.

From 1956-64 Olds moved to the Jetway that many of the brands used for their 4 speeds until they went away. IIRC the plant burnt down and they just went with the turbo-* transmissions.

Note that I don't see if it was clarified but the first page suggested that Pontiac and Buick engines were common parts they were not. Pontiac was flathead and the Buick was OHV. BOP moved to straight 8's in the 1930s, basically copying what other "mid-premium" brands like Studebaker and Hudson had done in the 1920's

Olds released the first mass production V8 on a body platform designed for a straight 6 in 1949. It did very well in Nascar that year and the song "Rocket 88" hit the charts in 1951. That mixed with the improvements in fuel allowing higher compression ratios lead to issues moving forward with the straight 8 and GM cars moved completely to the V8/I6 model by the mid 50's.

On the subject of Detroits; Not that the #v71 can also be run flopped mode in many busses where one set of cylinders was horizontal and the other was vertical or turned ~45 degrees. They also had inline models like the 6L-71 which was mounted horizontal. Also note that the 12v92 was just two fused 6v92 engines and the same was true for the 16v71, 12v92, 16v92.

Another a fun engine is the Ford Taunus V4 engine was a chopped down 6cyl engine. It was used by Saab and a bunch of forklifts. They did have to resort to a counterbalance shaft but it worked pretty well. Funny enough on Saabs that engine replaced a 3 cyl Crankcase-compression two-stroke engine. Because during compression braking you wouldn't be getting lubrication the transmissions on the V4 cars still had a knob which would allow them to "freewheel". For a fwd car those old saab 96/95s are some of the best snow cars ever if you remembered to not kill yourself overheating the brakes on downgrades other times of the year.

While I get that all of these forms have their fans and critics, really concerns like engine packaging space, consumer beliefs, vendor choices, and weight considerations drive most of the selections.

 

I have worked on a 671 mounted laying on it's side under the floor in the camel pro teams bus. It is a 69 model chassis that they had a new body put on . I actually worked on it twice, 10 years apart. lol That bus had the motor mid mounted, not front or rear, I walked all the way around it before I found the radiator. lol

What is a 1272, I have been around 1271's but never heard one called a 72 series, typo or something I have not heard of?

 

Oops, it was a typo. I had written a novel and obviously had a momentary lapse of reason while trying to make it shorter. Thank you for pointing it out as I never dealt with anything outside of the 71 and 92 series.

These models were built from end-to-end joined blocks. 16v71, 12v92, and 16v92.

There were some odd configurations of side by side 6-71s in tanks and ships but I forget what they were called.

 

I have been around side by side 671's in one dozer, just a little bit. A terex, but if I remember right, it was actually two dozers side by side and joined at the final drive, not the engines.

 

Found the tank example the GM 6046 from M4A2.

It doesn't look like the 16v71 were both sides are fully mirrors bolted together.

 

There is a truck on the north slope with two V8 side by side, I want to say they are 92's. I do not know how they are joined though. it is a big wide ugly thing with a fifth wheel sitting pretty high too. They call it Sal or Saul, something like that, don't know why. lol

 

Apparently the 4*671 was called the GM 6051 quad. Apparently the WWII LCI(L) ships had two of them.

 

They tried lots of corny ways to solve the power problem, like this enterprising young man, who bolted a Buick V8 with 3 speed automatic to the front of the IH 6 in this Diamond T. Apparently, it worked.

I'll rave about my powerstroke. That thing runs like a scalded dog! Tons of power . Gotta be careful taking off at the stoplights or you'll smoke the tires.
