    i believe nothing government models put out
    38 years dealing with the Fishery service (NMFS)
    they are headquarter in Woods Hole Mass
    Every new survey they would build a projection model of fish population. Each new model would have to be peer reviewed
    so some fishery biologist would fly over from Finland for a week review the data with NMFS fishery biologist then later they would go to Finland review his everyone got a vacation. the fly in the ointment was the peer review had to include at least one commercial fisherman that was engaged in catching whatever species was on the table at the time. Over the years I sat on 5-6 of these boards as the redheaded step child. Unwanted unloved and generally dismissed.
    The Mid Atlantic has a large population of weakfish In the late 90's it appeared they were being overfished and strict catch limits were put on them rightfully so. In the spring of 2000 between Ocean City MD and Virginia Beach Va you couldn't avoid catching some no matter what kind of fish you were seeking.
    Later that summer as I sat on the weakfish peer review looking at all the charts and tables of how the weakfish was a collapsed fishery with no hope of enough population to rebound. I asked if that is the case why were there so many off the VA coast.
    With a look of disdain the head of the review replied
    "Mr Morse if you really understood anything about these fish
    you would know they all came there to spawn because their numbers were at a all time historical low."
    I could find no words to respond to that thinking
    either the fish read the reports of their own demise
    i am crazy
    or government employees believe the koolaid they drink

    It's funny, after sitting ~2 weeks then coming back after a major repair you become hyper sensitive to the slightest noises. What is that rattle? Did it do that before? Is this drop of oil in my parking spot from me or the the last guy? Was the turbo this loud before?

    I've put ~1000 miles on it so far, taking 40k over Monteagle with no issues. The oil just started to darken so it's currently getting that changed. I'll probably do so again in 5,000 and then sample the third oil at 10,000 & go from there.

    Climbing (or descending) a decent grade used to unseat my dipstick, but no longer. Guess that means blowby is much lower now.

    I don't notice any more power, but I don't often use all 370 horses anyway. It seems to make more racket at lower rpm and less at higher rpm than its predecessor. It used to be pretty smooth from 1100-1500, but that range now seems to have moved up to 1300-1700. Then again, could be my imagination because I have no explanation for why that would be the case...

    With the new injectors and harness it idles smoother than ever. And with the new engine harness, I can use the jakes on a rough road without them cutting in & out. I'm looking forward to going down donner or the grapevine to see if they're stronger.

    Coolant gauge now reads ~183° compared with 188° before, but I'm chalking that up to a different resistance of the harness.

    I haven't run a tank of fuel on the inframe, so I don't have any mpg figures yet. My scangauge went TU during the break so I don't even have it as a rough idea (Linear Logic is warranting it, but I'll probably pick up a D to use while the KR gets repaired).

    I hear it can take 50-100k miles to fully break in an engine so I'm bracing for disappointing mpg at first. Plus I've been following old-timer advice and varying my speed. I've never ever encountered an engine that would only run right at a certain rpm, so I'm inclined to think of it as superstition, but what's the harm in avoiding sidewalk cracks for a while?

    the different speed stuff probably has its roots in a different era and older engines. Boat engines are really all the same as truck engines, Cat engines of the 70's didn't work well with the turbos
    of the time with boats that would idle all day like lobster boats
    Other boats like draggers could put the engine at 1500 rpm and leave it there for days on end
    advances in technology has changed all that now anyway

    The varying engine speeds and different engine loads is to get the rings to seat properly. Run it like you store it for a couple hours and you should be good to go.

    my mechanic would start the engine put it to 1800 rpms cold and leave it there while he picked up his tools. I would cringe in the corner

    Ya I'd cringe also. What I did on this engine after it initially fired up and idled back down is spend about thirty minutes running it at different rpms. Hold it steady for a full minute, then either speed up or slow it down a couple hundred and hold it. Repeat for a good half hour then it was time to load. Made sure my first load was pushing gross, and ran the Crap it off it for the first hundred miles. Winding it up before grabbing the next gear, and once to cruising speed every few minutes id drop out of top gear to get the rpms up for a few miles before switching back. I did this for about a hundred miles, and then drove it normally.
    Must of worked or Atleast didn't hurt cause it has almost no blow by and doesn't use a drop of oil.

    I read this years ago and it still makes more sense to me than anything else: http://www.mototuneusa.com/break_in_secrets.htm
    Driving for fuel economy does not make for a good break in. I would dyno break in if you can have it rebuilt somewhere with a dyno on location.

    I was frustrated with the mixed bag and unscientific break in advice for a reman engine.

    I've been going on the hypothesis that a certain rpm and power load is optimum for sealing up. Not knowing what that is, I just try to hit a wide range of driving conditions. I don't agree that you have to be abusive or hard on it to break in. Ram-rodding around isn't even that demanding on the engine, it's just hard on the drivetrain and suspension. Fully loaded climbing a hill @ 1600 rpm is the best way to put a load on the engine IMO.

    I have embraced the concept of not idling, either shut off or bump it up to 1000-1100.

    IDK if any of that really matters but with less than 20,000 miles I think mine is effectively broken in.

    I know a few that live paycheck to paycheck and they are the exceptions and the ones I am referring to. These few will never get a fair shake because according to you they are bad people because of their credit score.
