I just wanted something a little more peppy and more powerful. I'm kinda interested in a turbo kit for it too. I need to buy a new engine so I'm considering my options at this time. I hear good things about the 6.0 not sure if I need a bigger engine as I wanted to not go too crazy . I need someone to build me a good motor N/A that can possibly handle boost in the future If I thought the N/A wasn't powerful enough.

  • @keithlane4343
    @keithlane4343 3 ปีที่แล้ว +2

    Couple of questions from an old engine machinist.
    I sold my shop late 1980's and had a non compete clause in the contract, so I have never done any machine work on LS engines.
    Do you worry about intake manifold alignment dropping the "V" , milling so much off the head to deck surface?
    I understand the rocker assemblies are non adjustable on LS engines.
    How do you set valve lash ? Do you run shorter push rods, or do you add adjustable rockers to compensate for milling so much off the heads?
    I enjoy your channel. Take care.

    • @JacobVillemain
      @JacobVillemain  3 ปีที่แล้ว +5

      Yes I will most likely need to mill the intake flanges so the ports line up correctly.
      Valve lash is set with pushrod length. Now-a-days you can get pushrods off the shelf in .025” increments.
      Thanks

    • @keithlane4343
      @keithlane4343 3 ปีที่แล้ว

      Thank you for responding. Hydraulic lifters used to have .060 movement from no oil pressure to pumped up with the engine running with oil pressure, so you can get the lash set pretty close to mid throw with .025 of adjustment from the push rods. Interesting.
      I have one last question for you.
      When I had my shop, it was attached to a NAPA parts store.
      I know all the Allied Engine Parts part numbers for the parts I used to use to use to build small block Chevys.
      Unfortunately NAPA no longer sells engine parts according to my local NAPA parts store.
      I used to use valve stem seals that were attached to a flange that the valve spring would sit on so they couldn't pop off the top of the valve guides.
      Do you know if anyone makes those seals any more?
      The Perfect Circle tool I have leaves the valve guide boss .502 dia.
      Thank again for your help.

    Just wanna say that i am a huge cathedral port fan. Yes for a mild applications they make less peak power but low to mid torque is very instant and make for a nice drivable car! Did a ls3 cam n tune think a 232/236@112 cam, made 450rwhp and tuned a ls2 and myself and a few others praised its manners and all preferred the ls2 to its power delivery and smoothness! I will be doing first stroker soon and want to achieve fast airspeed into combustion chambers to achieve a lot of low down torque. Anyone who can give opinion to a 408 stroker to achieve a fast torque monster id like to hear!

    • @JacobVillemain
      @JacobVillemain  3 ปีที่แล้ว

      I agree, the smaller CSA on cathedral port heads really promotes a lower rpm torque curve. For an all out racing application though like what I am doing, you just can’t beat the larger CSA in the rectangle port heads. It’s all application specific though!! Many variables to consider

      @ironmike742 ปีที่แล้ว +1

      @andrewwilliamson1879 the most compression you can run on 93 is around 11 to 1. It also depends on the valve opening events, LSA, and duration of the cam. More duration and overlap can allow more compression. Also you have to have to be careful of the ignition timing. Technology has brought us a long way with being able to run more compression. Direct injection helps also because it cools the cylinders a little more. A real good cooling system is a big help.Hope that helps.

    Which cam was on this car? Which intake manifold?

    • @dennisrobinson8008
      @dennisrobinson8008 2 ปีที่แล้ว

      If the car wanted to make more high rpm power, but was constrained by the heads, having the new heads will make a huge gain. If it's setup for moderate power under 7000 RPM, and a long runner intake then the heads won't make as much as you think they should. So on one combo they could make 30-50 HP and another they can release over 100 more HP. With the old combo making 537rwhp on 402 cubic inches, I'm guessing it's a long runner intake such as the fast or truck, and the cam is not that "big", probably 228-235@.05". Something that power peaks at 6500 RPM on the 6.0L and 6000 RPM on the 402 cubic inch 6.6L. So my guess is a 30-50HP release. With 100+ additional with bigger cam and intake setup for power peak in the 7000-8000 RPM range. So 575 rwhp with current combo, but enough head for closer to 700 HP at the wheels with the right supporting parts. I'm guessing the old cathedral ports made 290-310 CFM @.5".

      @@ironmike742 have you ever heard of quench? When going for big power quench plays a big part of stable hp. Yea you can cut heads and not have a issue. We’ve all done it. But 80 thousands is ridiculous. And by the looks of his other video of the block he’s using flat tops. And you only have around 120thou clearance on ptv stock. With a stroker cam and 80thousands off that’s definitely ptv issues. I’m assuming he cut the pistons. Or done a piston swap. So he should have ran a dome instead of cutting the shit out of the heads. It’s better to run a thinner gasket. Or some piston over cutting the head any day to improve quench. it just doesn’t make and sense to do this. You risk running into bolting issues with intake. You are cutting alot of the deck off the head making it weaker. Not saying this doesn’t work. Because it does. It’s just the lazy/cheap way of raising compression. And my grandpa owns a machine shop we build 600+hp N/a Ls based engines almost on the daily. So just because this guy has a shop and a TH-cam channel doesn’t make him the best builder in the world. I’m sure if you ask him he will tell you a tighter quench makes for less detonation and less octane requirements. Meaning you can run 12.1 compression on 93 octane with a tight quench. vs a normal or larger quench you would have to run 100octane. On the same engine. With less chance of detonation..
