My one question is this ????????????????/


Why did GM not do it right instead of doing a half ass job on the cheap ???

The costs that GM incurred with all the warranties and bad press on the 6.5 surely was far more than the cost of doing it right in the first place.

Even the OPTIMIZER 6500 is a pretty good engine compared to the 6.5 from GM

Too many bean counters getting into the mix maybe
