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 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...

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.

Man, I've seen some blown engines in my day, but that's a bad one. Very sorry to see that. Chris's husband.

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

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.
