So this is a serious problem right?

You would bend/break a rod if it was hydro.

Sounds like retainer dropped or piston to valve clearance wasnt there.. over rev.. rod stretches a little.. piston hits valve.. breaks it.. rest is history.

So the chicken egg scenario is did the piston hit the valve cuasing it to snap off and this the damage or did it happen from the valve breaking/snapping and dropping in the cylinder?

Very good point Julio, it did over rev and wouldnt come out of first gear(happened at the track) then the motor just shut off. What ever happened, its not pretty.
Well, it wont be back together for a few more months.. What a shame.

Are you going to make it to bowling green ?

Looks like one of our old stock car motors that we leaned on a little too much. Just close the electrode on that cyl and head for the "C" main!

Thats serious carnage

Man that sucks ,hope the block can be saved..:frown:

That piston top next door looks very interesting. Maybe some clues there. Looks like there might have been some very unhappy combustion stuff was going on? One would assume that even the omnipotent alchy injection will have some limitations as to how much hp it can safely support in our mills.

I looked at all the Rust on the Deck and Cylinder and thought off all the junk on top of the other piston was corrosion.

Looked to me like it sat around a while.

Wonder what the plugs looked like?

That usually will tell a story as well.

And not enough alky will also lead to issues

I "think" that since the valve broke and started chunking out the aluminum head under a load, the chunks of aluminum got sent thru the motor and stuck to the tops of the pistons.
Notice its on top of the carbon buildup of the piston, if it was corrosion, the carbon would be ontop of the corrosion.
The motor was a fresh rebuild a few years ago, been running in the car for a few years.
I forget what it put down for horsepower, maybe he will chime in

It has a fast system and a dual nozzle kit from some guy in florida
