Diesel?

[67chevy_hotrod]

Kind of a random question here.. My neighbor has a 68 1-1/2 ton with what he claims is a factory diesel motor.. He is extremely knowledgeable regarding these trucks. He says he knows it was never a factory option but this one has it. I can't remember what the motor is? And I have seen a few tricks with diesel badges that appear very original looking. Please enlighten me?

Back in that era it was possible to special order most any engine in a truck from the factory for a very small additional cost. In the mid 70s a friend of mine ordered a Ford pick up with a Lincoln engine. I am not sure if it performed any better but it was what he wanted.

In a Dodge you could get a Perkins. GM had their own diesels, I'm not sure what else was available.

I recall from guys I knew with the GM diesels that they didn't last too long. they always ended replacing them with gas engines.

Hamjet is comparing apples to oranges The olds Diesel was not the generals best idea for sure it was a gas engine [or close] converted to diesel. Some were ok some were junk at best then in the early eighties came the 6.2 it was not really a power house that people come to think of in todays duramax's but they were great engine I had one in a 89 1/2 that I used to pull my car hauler trailer in between duallys and I had 300 thousand and it sat for almost 2 years I went to crank it and it never did prime the pump. Now the OP said it was a 1and 1/2 ton so it is possible it could have been a 53 series diesel or there was a GMC motor called toro flow. Jim

Say, "That's really cool. Can I look at the SPID?"

If the factory put it in there, it's going to be on the SPID.

Yea, the one I remember best was a fella I worked with around 78? He bought a brand new chevy pickup with the 5.7 diesel and it lasted about 3-4 years. It blew up. he ended up putting a gas engine in its place..

Agree with hugger if its a 68 1 1/2 ton then my money is on a 53 series Detroit 353/453/653 , prior to the 53 series it was a 71 series built by GM 371/471/671, had a 371 in a old A.C HD 7 dozer from the 40s and a 353 in both a 67 and 68 Dyna hoe '

I pulled the 353 out of the 67 and bolted it in a ford ranger , sold it to a close friend of mine 6 yrs ago and he still running it around. and they do live up to there nickname Screamin Demon.

That's what it was he said it's a toro flow. Please shed some more light on a toro flo?
