We are the Borg, your "Go das biggin shtickin for kangaroo choppin or go home" will be assimilated. It's distinctivness will be added to our own. Resistance is futile.
Be nice if cams were cheaper and easier to remove and install, then test them all.
Umm, have you ever met a Cummins? They don't do well with being assimilated. And there are millions of them running around. Dodge does well just to CONTAIN them, let alone fully harness and wear one out. Usually, the truck fails before the Cummins, so I don't think assimilation is an option... ... ... if you want to ASSimilate something, try Navistar..... they need some group thinking and logic. Oh, and need I mention any of the Cummins Big Cam Brotherhood?!?! Yeah, they've got big brothers, bigger brothers, and then even BIGGER brothers. Millions and millions of 'em. Don't think that's gonna work out for ya, but knock yourself out. Just don't expect me to swerve around your unconcious body on the highway. I drive a Dodge, but don't dodge much... ...
Well, if you figure the cost of the cam, and the fact that it can be done in a day, pretty easily, especially when your flushing the radiator and such, I don't think, as a percentage, it's that hard. Or, you can do what I do, and just buy a truck to put a cam in, and then sell it.

Nothing is a sales incentive like 2G's of torque pressing you into the seat. :-laf
Gobs of low-end grunt sounds good initially... however, from following high-horsepower 1st builds, this isn't always great. RonA comes to mind and his 1,200 hp 1st gen street truck. He's running super quick spooling Garrett BB twins, and has gone to great lengths to limit torque in the lower rpm range. Above 2,200 rpm may be semi-ok, but drivetrain parts simply don't hold together well when subjected to torque hammering. Unfortunately, I found this out the hard way on my '06. It's been waiting on a trans rebuild now for 8 months
Well, the money you save building a Cummins up versus a blown gasser, and the longetivity of the Cummins, pretty much evens itself out in the drivetrain. Laws of diminished gained fun... . something like that..... I can tell you all about broken shafts, twisted carrier bearing supports, broken tailhousing... ... but that's no fun, so I'd rather talk about how I pulled a 6x6 with no rear driveshaft, or buried my Dodge in a barditch trying to get a cell phone.....
