I had as a company truck an Isuzu P'up diesel 4WD with every option known to Isuzu in the 80s.  It was the best diesel ride I've ever had.  145CID or so pushrod engine.  Ran like a top, totally unbreakable.  Very comfoprtable on the highway, and the low transfer was like ver many to one - it would climb walls and pull stumps.  I was sorry to turn it back - after 270K miles or so, for a HiLux diesel.  I wish I had bought it, I had the option.

""The thing missed here is that the engines used in everybody's transmission test program are straight of the assembly line and considered a disposable item. They are typically run out of envelope for as long as at least that test requires. It is not atypical for a single engine to be used for multiple transmission validations. It is no surprise when they grenade. There is also another waiting on an engine pallet so the test can resume.

I could tell you stories of Detroit testing that would astound you.

In those days blowing an engine during a transmission test was not taken lightly. Unlike today, we were not a powertrain facility but rather a manufacturing plant in beautiful Saginaw. We did an extensive breakin procedure on each engine and treated them with respect (other than running the crap out of them). We did not have the luxury of having engines waiting in line. Before I graduated to the Tech center in Warren, we were able to remodel the dyno facility to an automated, programmable cell so that the transmission could be shifted and the engine was not always running at WOT. Even though it killed us at Chevrolet, we still stuck with Pontiac engines. As far as the Northstar, it was developed by the then centralized Powertrain group with application mainly meant for Cadillac. At the time I was Director of Engineering for Isuzu and we had a competing 4.6 engine as well. We were told to meet with the Northstar development group and decide on a common or
at least an integrate
d design. WOW,talk about not invented here syndrome (I won't mention the individual's name) but the Isuzu design was spit out and stomped on. To this day, I still feel it was a superior product.
