I'd hope it doesn't need 2500 rpm for proper lubrication. My truck hardly hits that when I drive it. It hangs anywhere from 1400-2100 in general
Agreed, I apologize for any confusion, and I should probably add some language to my previous post to help clarify a couple key points. First point is the listed 2500rpm is not a sustained rpm, but more so an rpm that only need be reached on occasion for splash lube to reach the intended locations. I can say I have not monitored, studied or researched the internal lubrication flows of a modern Hemi. I know a wicked smart lubrication expert and maybe he'll drop by and give a lesson in splash,
@Burla is the name, theres others too. But I've talked to him a bit.
Somewhere on your way to 1500 rpm your rig probably reached 2500rpm or very close before upshifting to the next gear, no?
Maybe you keep your engine under 2500 rpm as a rule and not only do you have cam lobes but your cam lobes are bigger than mine. It's very possible. At 80k miles, I'm pretty happy to have my cam lobes still get'n those valves open and hearing the sweet sound.
I'd challenge an idler to a friendly competitive wager on who's doing a better job at lubrication demostrated by who's lobes can lasting longer, but my stock cam is scheduled for an upgrade to a high performance, high lift cam from Greene Racing in the immediate future. Surely my lobes will be bigger after such an upgrade. Let me add not the biggest, that would be down right intimidatingly for those closest to me having to deal with it all the time. (I would like it, and she complains about **** all the time any way, so maybe...)
Second point being the 2500rpm is not a published spec. This was from me talking to another person who knew how to successfully do a cam swap with a roller lifter setup. Does not mean that he and I are correct. Plenty of assumptions are drawn, there is no doubt.
I have a 500ft driveway from there I turn onto the private, community, single lane two-track and immediately hit a non-conventional 9% grade with whoops. For the next 1000ft we hit it pretty hard. Whether it be -20f or +80f, hasn't really mattered, never an idled warmup (which is a big change in my thinking from yesteryear) I just make sure 2500rpm at least once however brief.
I have yet to rub a lobe off but I'm not done driving for the evening, so I may get one off yet.
I wish it weren't there, I hate that it's the first thing my trucks gotta deal with but I also make sure that she's been properly lubricated for the intense up-down action that I have somewhat coerced her into. Can't have any parts going dry at a time like that.
(That took me a hot minute to author in some fun, changing one paragraph for another. Might just delete it, a lot of it just for fun but the points conveyed, although I do digress. sorry for any previous confusion)
