    Looks like an old marine v-8 from the mid/late 20's early 30's to me but Im no marine specialist. It would look bad ass in an open wheel roadster.

    It’ a Chris-Craft designed and built engine, not a conversion, either an A-70 (200 hp early to maybe 300 hp in later versions) or an A-120 (well over 300 hp). Both engines 5” bore x 5-1/4” stroke, 825 cu/ in. These engines were built in the Chris-Craft plant in Algonac, Michigan. The A-70 was first made in about 1926 and the A-120 was made until WWII. Heavy engine – over 1,500 pounds

    Looks like that CC A-70 has been modernized. It has a modern heat exchanger on the front, a modern flywheel on the front, and maybe a modern gearbox on the back. Be a neat boat motor, but too big for a hot rod. Maybe build a Peterbuilt roadster like Leno has.

    Those make better boat moorings than they do boat motors. If you're on a small lake or you want to win max point for originality in a boat show, it's okay, otherwise it's a conversation piece more than anything.

    am i mistaken or does it resemble a couple of big wisconsin vee's spliced together?

    practicality be damned; some things are just cool to have, whether they work well or not! and that is definitely cool.....

    i'm reminded of the big C-C cruiser i saw being cut up for scrap when i first came down here (Charleston SC) in 1982... it had a pair of 413 Chryslers in it. dude was going at the hull with a chainsaw....
     
  9. Wow, that's one helluva crankshaft. Non-twist forging with bolt on counterweights... Cool stuff for sure!

    Thanks for posting this photo, please post it over on the Pre WWII photo thread guys need to see it. That is a great engine stand with full 360 degree rotation.[​IMG]

    That would look pretty slick in a Chevy Apache 30 with a rollback bed. you could haul anything and do a buck ten.

    You mean "on" an 'Apache 30 with a
    roll back bed
    '....not in. I've seen one
    of those engine 'up close and personal'
    before and they're massive. Forget about
    trying to stuff one under the hood, you'd
    need a truck at least that big just to haul
    that engine around on.:eek:

    If you ever think you have too much money sunk in your car, remember there is boating.

    Based on the excessive weight of the thing and its paltry power output I think I'd leave that one to the guys who are restoring old boats. I mean, okay, it might be a good engine for a vintage fire truck build or something, but for a hot rod? That thing weighs almost as much as an entire track roadster with a mildly built small block (from any of the big three) and the small blocks would be pumping out more power!

    And I sure wouldn't want to have to source gaskets, seals, rings or bearings for that thing.
     
  19. Good point.:)

    Similar to the two happiest days of a boat owners life? The day they buy it and the day they sell it?!:D

    Oops, thought it was smaller. Looks kind of small in the photos.
