    maybe the first Olds to do it...but Chevy did it in the 57 Corvette on the Fuel Injected 283.

    Mart3406, it's the M114 that originally had a 283 engine. Later versions supposedly had a Detroit. Here's a video of of the engine package from a military vehicle site. I'm thinking these guys probably know what was original? No idea if it was aluminum.
    Sounds like a gas V-8 not diesel.

    --------------------
    What in any way maker think that
    was a SBC?? That engine in the video
    link you posted is definitely a 6V53
    Detroit. Did you notice the size of
    the thing? Physically, it's about half
    again bigger than any SBC. Did you
    notice any spark plugs or any spark
    plug wires going to the cylinder
    head, visible ij the video? Nope None,
    Nada.Diesls don't need or have any,
    And the exhaust manifold port layout
    where it bolts to the head It's a
    spread-port design, totally unlike the
    port layout on a SBC. About the sound
    too 2-strike Detroits sound like they
    do, because they have twice as many
    firing impulses as a normal 4 stroke
    engine, so for any given RPM and even
    and particularly, at a dead idle, they
    always sound very "busy" and "angry"
    And the sharp snap and crack to the
    exhaust note is due to a 17 to 1
    compression ratio and a 23 to 1 on the
    non-turbo versions like the one in the
    video If that's not enough for you, at
    least do a Wikipedia search for the
    M-114 and see what they show for
    a power plant. I'll even post the link
    for you. By the way it;s the same
    engine also used in in current M-113,
    but just with a lower power rating .
    The very newest upgraded models of
    the M-113's use DDEC electronic
    controlled military-use-only version
    of 6V53's makes 400 hp at 2800 RPM.
    Almost double the original 210 hp
    rating of the engine and not too shabby
    at all for a 318 cubic inch V6 diessl that
    peaks at only 2800 RPM

    Photos of a M114 and it's Chevy V-8... Look through the photos and you'll see a side view of the engine looking just like the one in the video, with the same covered exhaust manifold.The valve cover says SBC ....

    Hmm. Corrected. Maybe they weren't counting the Fuelie 'Vettes as production cars? Maybe just advertising hype? Or maybe I just learned it wrong.

    Still, a scooting little coupe.

    Thanks for the right info.

    Don't know why they wouldn't. Even if you discounted the fuel injected engines, there was the '62 340 hp 327. It was the first Oldsmobile engine to make that claim, though.

    So, you still think the engine in the video is a Detroit? You still think the M114 was never powered by a 283? Is that your final answer?:D

    The engine in the video is not a Detroit Diesel, no doubt about it.

    I did NOT read this whole thread but if it hasn't been mentioned by me or other's, please look up David ray, (aka, "Ignitionman/Iman"), because if I remember right he has made a 300", 215" block engine for a Vega that he had.

    I had both, a 215" Olds and a Buick, way back then that I let get ruined so know a schosh about these engines.

    I want to say that the Olds had more head-bolts than the Buick, but, it's been years and years.

    I still have a Buick 4-barrel intake out in my garage because it's so small and cute, that I couldn't junk it for metal.

    And the Olds intake that I had was made to put a turbo hat on it because it was sealed up at the throttle linkage to withstand boost.

    The Olds has one extra head bolt.....that was the reason Repco used it for the Repco-Brabham cars. Obviously better head gasket retention. The Repco motor was built here in Australia and one version had the valley part-filled with epoxy to brace the block.

    interesting side note when comparing rover production to GM production...

    GM made more engines in this series in 3 years production than Rover did their entire production run!! Mind boggling!
     

  14. Or turn the oil pump..............

    I still have one of those manifolds too. The turbocharged Jetfire had a draw-through carb, not a blow through. The turbo manifold you have(which was unique to the turbo engine) was made to allow the turbo's outlet to bolt directly to the manifold. The hole pattern on it is for attaching the turbo, not for a blow-through bonnet over the carb.

    Just to avoid any misconceptions for someone who might be looking for a block, Olds and Buick used the same block. Buick just didn't drill and tap some of the bolt bosses.

    You could get a Vertex magneto for this engine, there was one on ebay a while back.
