When we use to Run 1/4 mi race cars we had a motor let go like this we ran aluminum rods and trying to save $ we ran the sets to long and one let go, But it did not go true the pan, it went up and lets say the only parts we reused after that was the pan & heads the rest was scrap.
So i say it was the rod that went out first and that made the cam get pushed out of timing and then you lost the rest.

Maybe the pin sheared and the valve hit enough to break it. a broken valve can cause everything that happened to his motor.

I would agree with SUX2BU, I think that maybe the pin tip sheared off. But SUX2BU (can't remember your name we've met in the past), you don't think there is a chance that when the output shaft sheared that the engine could have experience a big overrev?
In the old day of the LS engine, I broke it all, PtoV (just marked up the pistons) and I even broke a timing chain.
I don't remember already, but did you by chance break off an valve, any of them broken?
If you are looking for helpers on the car let me know, I'd try to swing by since you are not far. Looks like you need to source an engine hoist.

It's Juan, but half the people I know from the car world only know me as SUX2BU, LOL. Either is fine.
As long as the rev limiter is in place I don't think an over rev would hurt anything.

(wow, I sound like a drug dealer) probably can salvage some stuff from your motor..either way...can't wait to hear that your back on the road with her  |
I looked at the crate motor prices :eek: . With that kind of money you could get a LS3 bare block, heads, crank and throw some forged internals in it. Or you could spend about half as much and buy a low mile LS3 long block, you don't really need all the extra stuff the crate motor comes with (intake, coils, manifolds, accessories). But i understand if you want a warranty.
