    An 1100 cid Ford GAA V8 from a Sherman tank, or it could have originated from a marine application. Very cool old engines. They produced 1000 ft/lbs and 450 hp in stock form, used DOHC, 32 valves, semi-hemi head design, and multiple carburetion along with 2 distributors [6 wires each] driven off the head.

    Unfortunately, they are worthless because there are absolutely no replacement parts available for them that I know of... Not even gaskets. The NOS supply dried up a few years ago.

    With a 5.4 inch bore, all the regular piston makers wont touch it, and you'd be hard pressed to even find a machine shop that could facilitate servicing the motor on existing equipment..... Maybe a diesel shop [?]

    When people find one, they think they have struck gold... Untill they find out they cant get parts.

    How about the Chrysler Straight eights, 323.5?, or the Oldsmobile straight eights, these
    later were used in some LaSalle's ( I think). The Chrysler was used once or twice
    in a front engined dragster, sometime in the 60's. Neat engines.

    Yep, and heavy Chevy trucks used 322 Nailheads...wonder why. Hmmm...I know! Because they couldn't build an engine with the torque required to lug around a loaded tandem truck! hehehe
    Any time I get an opening, I'm gonna jab! :D

    I didn't think my set up was that "odd" at all until I tried to sell the car. Its a 250 in a 68 Chevelle and haven't had a bite on the car in over a year! Some folks like the usual SBC's a little too much I guess.

    The engine in the original question is a Ford GAA that belongs to a friend of mine. It came out of a Sherman Tank. GAA's were never used in marine applications. GAA's were a modified Ford aircraft engine design. The standard rating was 500hp and 1100 ft. lbs. with the factory governor settings. You did get the DOHC-32V part right, but they use a pent roof combustion chamber, not a semi-hemi. From the factory they use 2 magnetos driven off a combination gear-shaft drive system in the front cover, and they have 4 wires each (1 for each cylinder) not 6 wires each.

    As for being worthless, I guess your right if being able to get parts at Pep-Boys is important to you. There are parts out there, you just have to know where to get them and how to make the ones you can't get. I do have to agree with you on one point though, they are a little more difficult to restore or modify than a SBC. Here are a couple of pictures and links to my GAA.

    I bought my "first new vehiecle" a 66 GMC, 305 V-6, the long stroke made it a good truck engine but it wasn't too quick. After 32,000 miles I traded for a new 69 Chevy pick-up with a 307 V-8. After the new wore off it, I replaced it with a 327, the best engine that GM ever made.

    Hey now, those used to be my favorite crusty old sweatpants to work in. Sadly, I had to retire them not long ago, they are gone but not forgotten. :D

    Bringing this thread back from the dead...

    I'm thinking about building this flathead Cadillac V-16. It'd be a lot of work and I don't have anything to put it in (yet), but it would definitely be bada$$.

    The engine is all apart now. Here's a pic of the block.

    to find one of the duel v 6 six motors, check with irrigation engine repair shops. when worked as a farmhand in western kansas, i used to see them on irrigation pumps, lifting water from a 400 foot well. pretty unique setup.

    The picture of that tank motor poking up out of the hood of that Mustang is one of the coolest things I have ever seen.

  27. I have seen the GM V12s in tractor pulling. They work and sound great. Local frut company in the 70s here (Ontario Northland Fruit Company, trucking apples north beyond where they will grow properly) ran only them. The word on the street and in the shops was GM quit making them because they were too reliable. I doubt that but heard it about once a month from someone back in the day. Back then I did all the truck engines for the local Ford dealer where I worked. All were gasoline back then. In the few years i worked there we only had one diesel come into the shop (8V71 for a water pump.) 477 and 534 were the norm. Repaired about one per week along with my regular duties. Not all oddball engines are old. Here is one I am working in right now. And then there is my truck . Ist V10 ever ordered. My younger brother is installing a V10 into a 50 Blue Fargo 1 ton.
