Detroit 6v92

Should I run away from buses with this engine? It is a two stroke....is it very fuel efficient? Easy to repair/overhaul? I am sure that all of the smog laws would prohibit it if it were a newly released engine. And it is at least 600 pounds heavier than some of then newer engines.

Good engine, easy to repair, often misunderstoud. Not many modern mechanics have worked on them. They tend to be noisy. Nicknamed "screaming jimmy". I like them but not for everyone.

Noisy...probably because they are 2 stroke

Good engine, just don't overheat it, 2 stroke diesel Detroit's are not like 2 stroke gas engines, they do not pull the charge through the crankcase and have exhaust valves

Buses are noisy and inefficient. Embrace it.

It has gone through my mind to stick a 6V-71 in the shorty.... with turbo up to 300hp.

Personally I would prefer this engine to a lot of the newer stuff, very easy to work on once you understand how they work, all mechanical, super durable and resilient (as long as you don't overheat it as previously mentioned) parts are readily available nationwide. Sounds so so sweet, like a steel symphony.

What kind of a bus did you find it in?

I would love to see this! Found a thread on another site where a guy swapped a 671T into an old square crew cab Ford F350, was a crazy build, didn't fit under the hood, weighed as much as the rest of the truck. Just Awesome. I am getting a Crown and its like 75% for the Detroit.

I guess I will have to post some pics on the shorty when i get around to doing something with it. My wife is ready now to start on it....and I have been looking at engines for sale slowly....

You are certainly welcome to come up here and watch, might put you to work on it too.
