Oh man, that sucks. Any idea what went wrong?
I just built one for my '68 and I'm nervous as hell about starting it for the first time. |

Looking forward to the photos. Didn't this run rest prior to being taken down? I mean, it sounded good so I am guessing there was oil pressure then, was this under load or at idle when it lost pressure/bearings? If the pump is pumping and you have no/low oil pressure, a ton of bearings are no longer there creating a tight gap which raises oil pressure to get though. Curious if it's upper or upper and lower engine bearings, it sucks either way. Just trying to make light on a total bummer of a situation. Hopefully the cam survived the issue |

OP, what oil did you use?
A while back there was an issue using modern oil with old school flat tappet lifters. The results were just like what you had. The issue was the lack of zinc and they make several oils formulated for older engines. |

Sorry to see/hear about this. I guess when he put in "Street cam" he didn't exactly think it the whole way though.  |

Most new oils don't have the zinc in them needed for flat tappet cams. I run a high zinc oil in my flathead to keep the little lifters lifting. Roller cams are nice but I've had a roller lifter fail and send the little needles all through the oil system too. Nothing like breaking in a new hi-lift solid lifter motor at 2 AM with open headers. WAAAAAAAAAAAAAAAAAAAA!!!!!!!!!!!!!!!!!!

That's crazy the rods were loose. Like lose in that the bolts weren't tightened or loose from someone having the crank turned and not coming back in with the right bearings to keep clearance correct?

Quote HistoryI don't even know what to make of that. Will be interesting what you find when you pop the rod caps off. Some of those just look like rods with the wrong bearings in them, but that last one almost acts like there is no bearing at all, or it is missing one of the shells. What's the history on that motor? Either a kid rebuilt it and didn't know what was going on, or someone intentionally screwed it up. Only other thing that makes any sense is maybe it spun a rod bearing, guy pulled it apart and realized it and didn't want to fix it, so just hammered it all back together to get it out of his shop. |

Ouch, sounds like your oil pressure failed somehow, either the pump failed or the cam drive gear/distributor had issue.
No oil and the bearings/lifters/cam got ate to shit. I've been there, spent a bunch of money on a 383 and the distributor gear drive on the cam somehow lost a bunch of teeth... I had to have the crank and rods re-honed, new cam, new distributor gear and all new bearings. Why? a void in the cam casting. iske offered me a free replacement cam, so that was nice
