Probably not the best way to post pictures but here goes.

Also the heads, blower and its variable speed governor "maxed" at 2100rpm have been redone. It was built with standard pistons as well.

 

2100 is max RPM for an 8V71. I drove a lo-boy plus logging truck with one for about 2+ years and then spent decades working on them plus Cummins, etc. They may have been derated in horsepower for an ag tractor, but in diesel trucks the normal horsepower was 318 which is what they were commonly called, a 318 Detroit Screamer. However, for some reason I remember the one I drove was derated to 280HP. It's been a long time, but if I remember right, to up the horsepower to 318 you just advanced the cam timing gears one tooth and used different injectors. I remember we also maintained a stationary 318 at an inmate camp. It powered a huge generator that furnished the juice for the whole camp. That thing ran 24/7 near max RPM year in and year out unless shut down for maintenance. Tough old engines.

It was built with standard pistons as well.

Far as I know, that's all that's available, you buy new pistons and liners as a kit which of course is factory-standard.

You're definitely taxing my memory, there should have been a long 2" by maybe 10 or 12" sheet metal strip attached to one of the valve covers with ALL the engine specs on it for that particular engine.

 

Thanks LMJD, I attempted to post the data tag picture but I'm unsure if it went thru. To my understanding according to the serial number it's a 1948 engine and the data plate shows it was revised in 1959 however there is no telling what has been done to it over the years. We bought the tractor at a farm auction and it's to my understanding the old farmer is the one who re powered it with the Detroit. Some things were definitely done as a farm fix on it haha. I was expecting more power than 170hp with those injectors. I'd like to think the timing is set at standard however I don't know because the engine wasn't removed from the frame and the timing gears aren't easily accessible.

 

There is a forum member called Gone Fishen that knows about Detroit Engines.

 

Ok great! I'll look him up and test his knowledge, thanks!

 

He would be the guy, he freshly retired from a Detroit Diesel dealership in Vegas if I'm not mistaken.

Yep I got it!

I look forward to talking to you about this and hopefully you can shed some light on some things!

 

If I was to run a pair of turbos on my engine could I still retain my standard timing and us 92 series injectors since, or I have heard, they're advance timed?
