    Good info on identifying the 2 engines. This will come in handy when purchasing a loose engine off Craigslist.

    LS4s always trip up even hardcore LS guys. They forget GM made a FWD LS. They came with an all-aluminum construction with cathedral 243 heads. I love mine, and it's a pretty capable platform if you ditch the dog poo 4t65e trans. Great video!

    Always great Tech from Summit Racing. But I'm planning to upgrade the LS3 in my 2017 Chevy SS (made in Australia) with either an upgraded LS style crate motor such as the 427/570 OR even go further and drop in an LT engine (wet sump) but it would help greatly if you would confirm which Çruise & Connect Chevrolet Performance package would fit and work in my SS. An LT5 with an 8 speed auto trans would be ideal but is that a viable option? If not, what package would you recommend that would be simply drop in and run? Thanks in advance. Cheers.

    The debate is SBF, SBC, LS or an LT in the 71 Pinto Halfhatch.

    • @ispeakmurican4327
      @ispeakmurican4327 4 роки тому +2

      If you want unique, do sbf or LT, if you want inexpensive go sbc, if you want the most power for a bit more, go 6.0/6.2 LS. Yes a turbo will make good power with a 4.8/5.3 but the old adage is more cubes = more power. The only hinge is weight.

    ___ Thank you ___ I have a question if you or anyone with the knowledge could tell me please...
    I have a 99 C5 convertible Vette. I'm going to be building a motor and I have the upp twin turbo kit that I am installing as well...
    Would you build the original Gen 3 5.7 or a Gen 4 5.3? I plan on installing new pistons n rings as well as all nes bearings and a btr cam kit etc with ls7 lifters and trays .
    Why would the 5.3 block be better? I heard they have a stronger block compared to the Gen 3 LS engines.
    Thank you for any help. ✌️

      Cam sensor extension cable, Might need lingenfelter 54x to 24x box, and maybe some injector connector work. If the gen 4 has vvt and /or afm you'll want to deal with those too. Use the gen 3 oil pump (Melling 295) on the gen 4 after dod delete.

      No one knows what they are doing when it's their 1st time at anything, no matter what it is. It's only after you gain that 1st try/experience is when you gain experience, because you learn from what you just did. ✌
