Well, the good news, neither head was hit so they should both be alright. The intake is also fine. Umm......thats about it. Oh yeah, I have 6 good rods/pistons also.

Bad news, all the valves are more than likely bent. The roller cam was hurt. 2 of the valves hit the pistons hard enough it caused the roller on the lifter to shatter resulting in the cam getting damaged. It can probably be fixed by regrinding it to a small base circle, but, that's just more money on junk parts. 2 pairs of the lifters wouldnt even come out of the block so I left them in there. Of course the block is trash. The trunions in a couple of the roller rockers feel real bad, and more than likely need replaced. The oil pump is trashed, even the pickup tube was broken. The hardened shaft was broke, bent and twisted. The timing chain was broke, the teeth on both gears were damaged. Even the camshaft retaining plate that bolts to the block was destroyed. I'm sure I have forgot stuff, but, the list of "good" parts pales when compared to the list of "bad" parts.

I'll send some pics to Steve and maybe he can post them later. It's not a pretty site.

I was trying to think of something funny to say to lighten the load, but it looks like you got hosed pretty good. The best I could come up with is I bet your air cleaner is OK...

I did forget to mention that my MSD distributor is ok as are both valvecovers.

Something like that scares the sh*t out of me.

I can imagine doing that with a 4-speed... and having the rear tires lock up and skid through all the engine's oil at around 100mph or so...

Actually, I bet it got less than a qrt of oil on the track when it broke. It never punched a hole in the pan, or in the block. All the oil that got out exited thru the front pan seal. When the crank broke, it pushed the bottom of the timing cover forward and let a little oil out. And, the motor never locked up.

It was ugly, but it could have been alot worse. It could have broke at the finish line, at 107 mph and caused me to crash.

From the third picture it looks like the there was too much "HAY" at the top of the cylinder bore. This should be a tip for the rest of you "Never" overfeed your pony. I'm sorry I'm making light of your misfortune but there is a silver lining you were fortunate to not have got in your own oil, I've seen that happen before and it didn't turn out well. With that in mind I feel lucky that I only spun a rod bearing 2 weeks before the Las Vegas national event that Alex will be attending. Good luck on getting your Pony back together KV I'm sure the good members at M&M will help all they can if asked.

Daaayyyyummmm. I could see where you might be tempted to get away from the cleveland after something like this. That's scary.

It'll get better KV next year is coming soon and this season is almost over anyway.

time to start anew and contemplate motor combos.
I might know where another 351C block is.

hang in there buddy, racing is like this sometimes.

Pretty ugly, that is some major damage. On the good side, you are O.K. and so is the car other than cleveland, another good thing is, you have KK to help you get over the "Blown engine blues"

That's a sh***y deal

Kid, that's where mine broke too, between the first rod journal and #2 main. When I first told Evanuik about the crank breaking,his first question was "did it break in front of #2 main?" He said this seems to be a common point of failure for hi-rpm external balance Ford small blocks. I guess the crank actually tries to bend at hi rpm's, and this is the area where it's "bending" the most, and cast iron doesn't bend

Ouch.... that is some bad carnage.
Windsor cranks are known to break in the same place.
Good luck with the parts gathering.

Mark, the hay is tuff to get thru the carb too! Plugs stuff up!

Since that crank was run in a block that had the #2 main webbing broke, I'm sure it had flexed quite a bit causing an unseen crack to develop. I still don't beleive it was due to it being externally balanced, and neither does Animal Jim. We both beleive it developed a crack from being run in the broken block and I never caught it (that tends to happen when you don't have them magnafluxed aftrwords.) That is the lesson to be learned here. When a motor is run with any kind of problem, even if everything looks alright, have it all checked thoroughly anyways. Otherwise, this might happen.

When KK's brother broke his stroker windsor crank several years ago, it broke at the back, and it did wipe out the cylinder walls. I beleive mine being filled is what kept the bores intact.

The real sad thing is, this motor ran the hardest of any I have built so far. And when I pulled it apart, the bearings looked like new, better than any other's previously. It was definatley a sudden destruction, and not something that happened slowly over time.

Hey kid you might want to try and have the next crank cryogenicaly treated (cold treated instead of heat treated). The one in mine was done awhile back have about 1000+ high rpm (8500+ rpm) passes with no wear, tear or scuff marks.The rpm is just bad on the valve train. They say cleveland cranks cold treat very well. Makes them more forging than fordged steel but just as tough. Sorry to hear about the loss of another good cleveland.
