    LT 376/535 Crate Engine

    Looks like the LS engines are going obsolete.

    I'd say that's bait to start me going.

    The cam specs on the LT376/535 and the LS376/525 are very similar. LT cam is a fuzz bigger and could be the sole reason for 10 more hp.

    Cartel price on LT376/535 = $11300
    Cartel price on LS376/525 = $ 8229
    Cartel price on LS376/480 = $ 7186

    Prices on controllers:
    LT376/535 = $1951
    LS376/525 = $1177
    LS376/480 = $1141

    So the LT 535 hp engine with a controller is $3845 more than the LS 525 hp setup and $4924 more than the LS 495 hp setup. Nor exactly a value deal yet.

    On top of that, LT engines don't have power steering pumps on their OEM accessory drives, as the vehicles have electric power steering. Just introduced at SEMA from Holley is a set of adapter plates that uses an LS water pump and an LS Holley accessory drive.

    There's no oil pans suitable for swaps yet. Also there's no offerings for tube headers for swaps yet. I see there are engine mount brackets available.

    I'm sure there's some advantage to the LT376/535 over an LS other than 10 hp, but it can't be much other than bragging rights for the latest naturally aspirated crate engine offering.

    More aftermarket parts availability, used engine availability, etc. will be needed before this is a real deal rather than "me first".

    The supercharged LT engine has more of a power increase over LS with supercharger - plus way more power than NA - so those will be the ones you'll see in high end cars.
