  • Can we make more power with less compression, less duration and less head flow? This Vortec headed 355, I call the Dingle Ball 2.0 is put to the test on the dyno to show we can make some great power with a roller cam VS Flat tappet.

      I'm traditionally a Big Block Mopar/Big Block Chevy guy, but.. I've recently stepped into a jet Boat project that's gonna be powered by a 6.0 LS. Totally different animal, but wow.. the parts availability and ease of making good power with the LS platform is hard to deny. High performance roller cam and lifter kits from Summit for less than $450 !! And the heads flow amazingly well in stock form. Power with an LS is like shooting fish in a barrel... pretty cool in my opinion. 🍻

    You have proven again that you can run a noticeably smaller roller cam and make similar power to a larger cam. The Vortec heads always amaze me in that they a lot of times make more power than a better flowing head. That’s one nice thing about small 170cc runners flowing 230 ish com.

  • @zachniverson8816
    @zachniverson8816 Před 13 dny

    I think you should definitely use the 2.0 heads and cam on a 383. But also use an Edlebrock rpm air gap thats port matched and the ports cleaned up with that same spacer. You'll gain SOO much more low speed torque and with the porting and spacer you wont lose very much top end at all compared to how much youll gain down low. Also I would raise the compression back up to 10.5:1 and run 93 octane for all of us that do have 93 at the pump. I believe youll see 500hp or close to it peak but lower rpm gain will be impressive. I woukd really like to see this combo man

  • @bdugle1
    @bdugle1 Před 24 dny +2

    I’m guessing that hp carry at the top on the “1.0” engine is the longer exhaust duration. The fatter torque curve on the”2.0” is probably the bigger lift and more area under the curve of the roller vs flat tappet cams. I like the 108° LSA, I don’t remember if the flat tappet cam was the same, but that could fatten up the mid-range too. For myself, with intake closing in the mid 40s (at 0.050”), I would take the 11:1 build. All together very nice work! Thanks!

  • @robertwest3093
    @robertwest3093 Před 23 dny +1

    Did you use the thick old style 5/64 thick piston rings? I would love to see a test between them and a 1/16 or 1.5mm set and also a 1mm set. The only tests I’ve found haven’t included the 5/64 rings. The OEM’s went to 1/16 or 1.5mm in the’80s and now a lot of engines use 1mm-1.2mm sets. I would imagine the difference between the thinnest and the thickest rings would be 10 HP I would imagine.

    Both awesome engines.
    I have a 377 version I'm going to be putting together soon. 4" bore 3.75 eagle rotating assembly. With some after market vortec heads from jegs. The pistons do have a dish. I think 7cc. And are .020 in the hole. But with the 64cc chambers and a steel shim headgasket it should still have decent compression. Comp cams

    The people worried about 11:1 on pump gas don't know anything about dynamic compression ratio. That's perfectly safe and you can push it even further.

      Cam overlap and bleed off have a big influence on what compression can or can't be tolerated.

    A 235/241 hyd roller cam will act like a 247/253@.050” hyd flat tappet cam.
    Don’t remember what the dingle ball 1.0 had for flat tappet hyd cam specs.

  • @poortouringhotwiregarage5617

    90% of the time when flat tappet cams go bad on a rebuilt engine it's because people don't hone the lifter bores. Lifter bores usually get scored during tear down, which keep the new lifters from rotating. If the lifters don't rotate while the engine is running, they WILL get destroyed along with the cam lobe.

    • @cuttersperformance

      And can possibly become egg shaped over time or because of heat. Hot tanking specifically. I've been preaching to people to have their lifter bores honed for years and years.
      But, that's yet another reason to go roller.

You should do a 305 the engine nobody wants but surprisingly the combos and stroker option is quite unique. 400 crank on .040 or .060 bored 305 or 327 crank with dome piston and rod combo with 350 vortec heads 🤔 interesting.

    • @cuttersperformance
      @cuttersperformance  Před 24 dny

      You can, and I have done 11:1+ on SBCs but it's not quite as easy as LS platform. The LS heads are very efficient and require less ignition timing, and the cooling system of the LS allows better coolant flow through the heads to prevent hot spots and cooler chambers. Back when GM built the 11:1 SBC the gas was much better than today, the timing often times needs to be dialed back to run todays gas without ping

    • @HioSSilver1999
      @HioSSilver1999 Před 24 dny

      @@cuttersperformance yea the old sbc chamber might not be quite as good as a ls. But a vortec or lt1(90s) is probably close. I ran 10:1 on with a 406 and l98 heads back in the early 2000s. That was in a k5 with no issues. Not even a very large cam.....small really.
      I think most the stuff that had pre ignition issues properly also had a dish piston and/or a large chamber which screwed up the quench causing issues.

    Aluminum head needs 1-1\2 more compression to equal an iron head. Around 11 to 11-1/2 to 1. Aluminum dissipates heat faster, and it needs the higher compression to make up for the lack of heat in the combustion chamber for a better burn.
