    Dave, my Denali didnít quite do that good, but going to Phoenix last year, it did this. I set the tripometer when I hit IH-10 about a mile from my house.

    I just reread your last line re "averaging 70mph over 600 mi"

    That IS frickin' impressive in it's own right. We do that sort of stuff.... my personal record (well, mea'n the wife, straight thru) is 87.78 figured olde school from driving 1861 mi in 21hr-12mn but that were in a car where I remember running thru at least 3 tanks with the cruise set at 126mph

    You were smouldering to get 70 in a Denali my frien'!

    You made some good time there Jackie. Is that the 6.0 or the 460hp/420tq 6.2L?

    It took about 8 months for the hamstring to quit hurting. After that i could finally lift my leg high enough to get my jeans on. Still getting stronger.

    Thanks for asking, but no more working for me. I sold the Iowa division last May and the Illinois division in June. It was a two year process working with multiple buyers. Drove me crazy. Wished I would have done it 10 years ago. I have not missed the business one second. Looking forward to doing stuff with the wife, shooting, and racing more. Did lots of stuff to the car this winter and should be going to a T&T in a couple of weeks.

    Itís a 2018 model, it says 435 hp 6.2 liter. Itís by far the nicest truck I have ever owned.

    The good thing about my trip to Phoenix is I get on I-10 about a mile from my house and donít get off until I hit Phoenix. And once past San Antonio, itís 85 mph. That means everybody really does about 95

    My little bro-in-law (funny, he married my little sister who useta' be 'wayyy younger than me, like only 6yrs-old when I left home.... now they've got married kids....) but anyways, my brother in law was recently bragging that his new Denali would just CRUSH my old beater Suburban, that it had more horsepower etc and I thought he was just egging me......

    Now I hear you'se guys...It probably does have more horsepower if it's that 460hp version!


    LOL

    Jackie, I love I-10 through Texas, New Mexico, and Arizona. I believe you can average 70 while driving the speed limit on that road.

    Regardless, we all like to limit the amount of oil going up top, but no oil in the top is not a good thing

    I love to see engine specs. As you know, power is made with four things. Cubic inches, head port flow, cam specs, and compression.

    I figure they have around 13 to 1 compression, 274 degrees of duration at .050 and .780 lift, and heads with intakes that flow around 450 cfm at that lift.

    Thatís about 950 HP at 6800.

    Just curious. How close am I.
    Jackie, the block has been done with unbushed .904 lifter bores. Camshaft is a 308/318 @ .050 with .805/.780 lift on 114 lobe centers. The previous lifters were Crowers and the new ones are Morel. No indictment of the Morels...they're high quality pieces. The proper steps just weren't taken to provide adequate top end oiling. We juggle this all the time, especially with the Dart blocks.

    I don't have access to the head flow numbers but they are conventional 24 degree R-M's with a 355 cc intake port. I imagine flow would be around 427/300 cc for these.

    Thatís a tad more serious than I guessed. I should revise my HP estimate up quite a bit.
    And the RPM. That sounds like a 7800+ rpm setup.

    Yeah, it should make 1,000 for sure....950 with a really safe tune.

    When it was 850 on the first pull, we knew there was a problem. -Al
