Classic example of poor machine work..
This thing snapped the crank in half, cam in 3 pieces. Attach file:  419790_2355053694379_1791312576_1559501_145917741_n.jpg (22.82 KB) |

Blurry picture is blurry.
I see a 4 bolt main. What am I supposed to be looking at? Was it not torqued down and you found the main bolts that loose? |

Is that a spun main bearing? Friction increased until crank seized suddenly, causing the massive breakage and failure?
PS - Guys, let's all get a few bucks together and send Engineholic a digital camera for his shop so he'll stop posting up blurry camera phone pics. LOL. |

I'm sorry bout bad pic's... adding pic's is all new to me ;(
This 383 only had one trip out racing (NOT my work), any how customer brought her in to me, upon teardown , it was obvious that the mains had been line honed....Problem here is that the caps were looser than a goose in the block registers, they were walk'in front to back, side to side...Felt bad 4 the guy. It's toast!!!!!!!! |

Remember, it costs a lot more to build it right the second time than to build it right the first time!

what we don't know is what that person paid for that engine. I agree, under normal conditions, you would think cut rate, but the parts were pretty good stuff, just put together like crap.
so... who knows... |

Another error here is that he used a stock cast crank....If he woulda ran a nice steel crank the crank would have stayed intact, and possibly this assembly may have been salvagable.. The block wasnt envn clearanced enough for the extra stroke!
