    Check this out......I found these pics and text on a dirtbike website. The question is can this contraption be made to run????:eek:

    "This "v-twin" started out life as a standard small block 350 cubic inch Chevy motor found in zillions of trucks and cars for decades. The builder (no, we don’t have a name for you yet) simply cut the back two cylinders off and created his very own v-twin. The back cylinders are used because that’s where the distributor is located.
    Naturally, a timing cover and crank damper had to be added to the front of those two cylinders, and the shortened valve covers had to have capped ends fabricated. Note that the stock starter and flywheel assembly are retained."

    There's a guy here on the HAMB that goes by Dr. Frankensickle that has a BB Chevy "sickle" that is done like that. I haven't ever seen it myself but I've heard about it a lot since he is local to me. I know his runs. My Friends have seen it.
    Maybe we could get him to post some pictures. I've heard it sounds real mean too.

    Someone told me years ago that there was a commercially available, somewhat more conventional looking, V-twin using special castings but based on 400 Chevy rods and pistons, nature of upper end not known. Anybody hear of that one?

    I think I saw that in one of the magazines way back when. If memory serves right he built it for either a hill climber or a drag bike. It would be one of those things where the builder would have to have access to a fully equipped machine shop and the skills to use the equipment.

    At the time that was done your choices were to modify a Harley knuckle or Shovel head or an Indian which were flatheads.
    They didn't have the aftermarket big inch V Twin engine builders that they do now. S & S didn't come into existence untill 1958 and then their first products were high performance push rods http://www.sscycle.com/iframes/history.php The complete engines came quite a bit later.

    Lots of V8s have been cut down to fit in LSR cars to fit in specific classes.

    They run a v 8 chevy cut the long way and the short way, v4 in midgets so it will probably work if you can oil it.

    Does anyone remember the Chevette that was in Hot Rod that has a V-2 Chevy in it? It got some ungodly gas mileage.
     
  21. Had a local guy make his own using the front half of cylinders 1&2 and the back half of cylinders 7&8. He welded it together and then sleeved the new 2 cyl sbc. He did the same thing with the heads.....kinda neat, put it an old hardtail rat bike about 1978-79.

    Ugly as sin, greasy and leaked all over the place but always drew a crowd wherever he rode it....and boy did he rack up miles on that thing!

    I remember seeing the Super Vee a few years later in SuperCycle mag. I also remember someone making a new center case for your Harley so that you could go to a 4 cylinder. Split you cases, insert the center case and new crank rods and add a set of jugs and heads. I think Rivera Engineering had something similar and more refined. Fueling head or something like that.
