    So what do you think, AWD turbo big block COPO truck?

    • @brandonbranecki3853

    • @ryurc3033
      @ryurc3033 2 года назад +2

      Transfer case, stock front diff, seem to take most turbo combos people are building, I would be curious to see if it can handle the torque. But at the same time it's a solid combo already. It would be easy enough to sell that one as is, and build another with a big block....I mean there's only a million of those trucks around.

    I only just discovered this channel, but I love it! And that you're talking to Topolinski makes it all that much better. I especially love that you asked him about horsepower vs. boost, and he thinks for a second, and says, "20 pounds of boost will get you 1750" without doing a single calculation.

  • @jerryburdick8051
    @jerryburdick8051 2 года назад +1

  • @jimmyjones8311
    @jimmyjones8311 2 года назад +3

    If you want to get rid of the COPO, instead of selling it. Detune and raffle it off. Then it would go to a follower that may not be able to purchase it outright. I know I’d buy some merch for a chance to own it. Just an idea.

  • @PANTYEATR1
    @PANTYEATR1 Год назад

    Shout out to Mark and the Bullet cams team. LT, I'm late, but would it be wise to degree the cam for low RPM power and let the turbo carry on the power from boost threshold to the upper RPMs? Basically letting the cam do the work down low and the turbo do the work up high.

  • @willkincaid5841
    @willkincaid5841 2 года назад

    Pat is to cool and he knows all kinds of stuff, i love watching their channel doing builds and then dynoing them. My favorite part is when they start testing all kinds of different off the shelf parts. It's nice to know what works of the shelf with other parts.

    My personal experience with cam degreeing, I like advancing the cam timing 4 degrees. Did that on a 80' evo harley, a 460 BBC with a 270 degree cam, & a 468 BBC with a 312 camshaft. You aren't wanting to turn big RPM's with this engine, and you don't need to. There's no replacement for displacement. And the engine will last years longer by not spinning it so hard. My 468 lasted 12 seasons on the dirt track circuit without needing a freshen up, and I chipped it at 7000rpm's. It usually never turned over 6400.

    No replacement for displacement! This is awesome,reminds me of the Viper Truck build from powernation! I'm so happy with my Viper Truck cam swap,I couldn't have done it without your help. I'm glad I didn't have to set the timing like this though, seems so tedious,but so crucial! Cheers from Canada!

  • @anthonysilva4410
    @anthonysilva4410 2 года назад +1

    I've always remembered a quote I read in Hot Rod magazine from the late great legendary engine builder Joe Sherman. He said you advance, or retard the cam timing to get the highest cylinder pressure and it should make the best power. Of course this is simply a tuning tool and not set in stone. It's something to play with when you are chasing power.

  • @Metalwolf765
    @Metalwolf765 2 года назад +2

    I think the engine here makes more sense in the longer wheelbase truck. It’s better for traction and stability. Besides, the “COPO” is cool, but would destroy the AWD system with 1500hp at the wheels. I’d agree- probably time to let that one go. I was more excited about that suburban you rehomed. A big off road SUV with equally big power would be rad.

    • @DM-qp7do
      @DM-qp7do 2 года назад

      Agreed 👍 I have a 05 GMC Sierra 1500 4 door with possi, and a 07 Classic Silverado short bed single cab with possi, when I smoke the tires the GMC is very forgiving for a long burnout but the single cab i have to stay on top of it or I'll be pointing the wrong direction in a hurry.

      Stapleton42 has a 6000lb full size AWD Escalade with 2000 HP running 9s In the 1/4 mile. He hasn't had any problems with the AWD system. I think it would be great to see a turbo 427 LS in the COPO truck.

      And they already make the LSX 454 block! The parts are all there to do a limited production run, like 3000 trucks, which the dealers can then mark up about 50 grand, like they do with ZO6s. 🙄🤨

    • @MRMechanicRC

    @trdscfjc 2 года назад

    After how many miles do you expect you will need to regularly adjust the valves? I've see .680 lift Hyd Rollers. A small reduction in lift to never have to adjust valves seems like a easy call. I've also heard folks have had alot of luck with the new CompCamp Evolution/short travel lifters.

    The COPO truck is pretty sweet as it is and it seems like it achieved all your goals at the start. The big block in the ugly truck is the bomb, big ugly power in a big ugly truck! Maybe it is time for another ride? Do you have any videos or recommendations for picking a cam for a 97 vortec 5.7 with roller lifters and cleaned up stock heads? I am port and polishing them and will use a carb on a 74 Jimmy.

  • @Mattmazz77
    @Mattmazz77 2 года назад

  • @sc358.
    @sc358. 2 года назад

    Gonna be a really cool build
    Those standard style heads? 24 degree w/ 2.3 - 2.35 valve? If ya ever do another cam swap down the line I'd go to a 109-110 LCA. 535 NA probably about 105 as a baseline but with boost... think a 109-110 but less duration for the same overlap would make more power. If you were running 12 degree heads I'd have the wide lobe separation, even wider with a hemi

    • @sc358.
      @sc358. 2 года назад

      Probably should've asked CR as well
      More cr, wider lsa after a point but I'd imagine this build is sub 11.5:1
      Also if ur running something like a 60mm+ cam (more agressive valve action) you'd spread the LCA
      Main thing is what kinda induction (flow capability but perhaps more importantly cross flow capability between intake and exhaust) vs the kinda cubes it feeds.
      For a given situation
      More cross flow & flow capability = wider lca
      More cubes = tighter
