Well, it looks like they didn't spend a whole lot of time trying to get the valvetrain geometry right.

I think I know what's wrong in this picture but maybe you guys will see something else here as well.

Well atleast we know where the piston material ended up.

If you're referring to the stuff in the bottom left, I think that may have just been some craps that fell in while taking it apart. There was a bunch of loose whitish locktite all over the rocker pedestals and white crap all over the water passage in the intake. The piston material seemed to be much finer. More like powder/ dust. But hell there's an even more obvious thing

push rods are miss matched

Bingo. The silver ones are Smith Bros. Pushrods I paid for. The black ones....aren't

This might be what's in the lifter valley bb. I don't know much loctite is usually found but most of mine looked like this
|
That sucks man.

Where's this all headed bck
|
Multiple places. Wanted to show the damage just because people like looking at stuff. Maybe some people will learn something. Trying to learn the exact cause of the failure so it doesn't happen again. I didn't detect any signs of detonation while running, so if it did detonate I have to make sure it doesn't happen again. Lastly to show the quality of the work this guy did so know one else has this happen by going to him. Even if I'm to blame by getting them hot that is no excuse for this type of machine work and piss poor assembly. The pics don't lie. The bearings can be seen, as can the valve geometry and the pushrods. I'll post up the pics of the pistons when I get home. Every single part on these engines were brand new purchased by me. Crower, JE, Smith Bros, AFR, Jesel, Pro Systems, Morel, Dan Olsen. Even though it's not all ruined this guy treated like junk from his garage floor
