John I don't know about all that stuff I know if it works or if it doesn't and I try really hard not to change stuff that is working and and just keep it the same. The best I do is to have someone replace what isn't working or fix it so it does what it is supposed to do.I replace an 8V71 that was dying with this L10 so instead of worse than 265 hp I got somewhere around 275 hp not much of a bump up BUT it quit over heating leaking oil and I added an automatic trans. For me it was a good improvement and now my girlfriend drives it some too SO EVERYONE is happy. Gary did a good job on my install and I can understand how someone would not be happy with LESS power instead of more even if it quit overheating.Melbo
Given you use of the technical term "that stuff" you don't have much of a passion for matters mechanical.
