I can't speak for the other engines, I've never owned one, the LB7....guess I'm too cheap...:roflmao::roflmao:
I have 2 LB7's...BLKMAX and Emma. I think the reason folks like the LB7's is because there are more LB7's on the road than any other engine model. No other models ran for 3.5 years.
All I know is that the injectors in the BLKMAX have been replaced 3 times (I KNOW that, I bought it new February 3, 2003). I know Emma's have been replaced at least once (I have the dealer receipt). The black truck is at 160,000, Emma is at 216k.
Both still run good... One runs harder than the other :roflmao::roflmao::roflmao:
All I can say is it is nice to have 2 trucks with the same engine and transmission!
