    Cool

    Somebody sure put a lot of time into that shortblock. 4-bolted the block with aftermarket steel caps, polished beam section of the cheapo offshore rods, coutoured and gassed the crankshaft. I can't tell you what brand the crankshaft is, but I don't believe it particularly matters since somebody was wise enough to give the parts a full once-over.

    Is this for that big 1471 blower motor? If it is, I would buy some insurance and replace the rods with something high end in steel, like an Oliver billet, Carillo, or equal. The crank looks very typical of what is coming out of China these days, contoured, gun drilled, imitating the high end stuff at half the price. If you were running blown alcohol, and really leaning on the motor, I might question it, but if it's for recreational lake use like I think it is, I would run it and not think twice about it. I have a feeling you are going to be running sustained higher rpms though, and would really want a best of the best connecting rod in there. My $.02.

    I think LDE is a Chinese mfg company that makes big diesel generators.

    I did find something on the front counterweight. Looks like-

    Jay Marshall m.2.7486

    Lambert Ent. r.2.1986

    Bob #2380

    The rods are Child & Albert I-beam

    Are you putting that big blower to it, and if so what is the target h.p. your looking for and what rpm range? Childs & Albert is a name synonomous with high quality parts indeed, but I would want to verify with them that those particular rods are up to the abuse level you are going to throw at them. Your boats aren't flyweights and you run them long and hard, I would just hate to see a failure that could have been prevented. F1~

    I'ts for the turbo motor in our 240 Hallett. Looks like the build date was in 1986 which make me think it's an american crank. The C&H rods are rated for 1,000 hp from what I can find.

    Gary Harabedian could probably give you a little history on that. He was buddies with Jay Marshall and Dale Lambert builds all of Garys engines.

    It's not likely those rods are good for 1K hp with the through-bolt. I'm not saiyng it's not possible, just not likely.

    Excellent point BamBam!

    Bob,, I can put you in touch with Gary, got his number on my cell.

    "bob" on the crank is the bob weight, and the other numbers indicate that it is (or was at the time the numbers were engraved) STD/STD, although it is maybe .0005" undersize.
