That's pretty cool. I believe Car Craft has a monthly photo contest of fuck ups like that. Should forward that picture to them.

(Knock on wood)
I've never had a motor let go due to an 'error'*
Double, then triple check all tolerances.
Including clayed piston crown valve relief mock-ups
Also includes degreeing any/all camshafts
Valvetrain geometry, blah blah blah.....





* excludes the 'error' of a missed shift

Who in their right mind builds a stroker motor and doesn't at least clay the damn pistons and valves.  I guess that's why they went out of business.

Thats a wall hanger for sure.

Been there, done that.

I had a piston eat a value on a straight 6  because a 40 cent keeper .    still have the value   it cured to an almost perfect ring.      piston was gone . was able to sleeve that cylinder .   head  didn't fair so well...... had to replace that.  

I remember Dale Sr.  losing a Daytona 500   because of a rotor cap.   and going on about   a 100 grand motor  and the least expensive part  is the one that failed.

reminds me of highschool small engine shop..

guy brought in the family lawn mower and did what ever he did..

brought it out back of the shop for it's test run....

started great....but it kept getting faster and faster... then  BANG

put the crank right through the case.

That sucks OP, but sounds like the shop will do right by you

I've had my share of minor screw-ups, and I have to cuss out the guy in the mirror for causing them

Suspend that in a clear resin block for a kick ass paper weight



Sucks other wise

Looks like it was beating itself around inside the cylinder before it impaled itself in to the piston.  Bet that made a bang.  How had are the cyl head chambers?  Heads saveable?
 



EDIT:  nvm.  I see its really old news.
Link Posted: 8/31/2015 5:50:16 PM EDT
Yep, pistons and valves don't like to kiss.   Have seen it a lot on big diesel engines.

Amateurs... LOL.

We were breaking an engine in for the race car once



It was singing along nicely then all of the sudden, blub blub blub blub




Ran into the garage to water pouring out a header




Broke a valve and cracked the block.




Don't know exactly what happened




That block got sleeved and put into my 4x4

I dropped a keeper on a 455 olds at about 3500 rpm, valve and piston pieces everywhere.
Link Posted: 8/31/2015 5:59:48 PM EDT
Be thankful OP.. this motor just loved spending my money..and when you get into BME billet pistons and rods, titanium valves and such..it gets spendy fast...


but damn was it fun....

SBC turning around 7400 when we discovered the machine shop didn't weld a weight they used to balance the crank. Basically had metal rod sticking out the side of the crank at 7400 eating everything in it's path.

Well........they used to until everyone kept destroying them....

I killed a 427 windsor stroker in the waterbox at the track.  

Best we can tell it was a couple failed injectors.  




Beat up one of the dart heads pretty good.


After some clean up and tig work the machine shop shaved it IIRC about 7 thou.  They said the tig work looked very pro.    
The monkey running the tig is far from a pro.  


A new set of pistons was all that was needed,  But it was decided to de-stroke it to a 413 with a new crank,  rods and pistons.  Even after de-stroking the motor it is faster at the track than the 427 ever was.  But I miss the ungodly torque it had,  And it is still no slouch on torque.



Listen to the death rattle.

Crazy, just enough to break it.
Link Posted: 8/31/2015 6:22:25 PM EDT
get back to me when you do this, none of the internal parts failed, the block just split in half

One of my old bosses wanted me to install a slug radially once.

I politely declined. So he installed it, as far as I know, engine is still going strong. But radial installation of Mallory or other metals on cranks is up front on my list of "shit not to do when building an engine".

I did that to a small block once, but the only pieces salvaged off the entire long block was one valve cover and the intake.. it let loose at just over 8000 rpm.... guy behind me said it looked just like a nascar  motor letting loose at the track..big ball of fire, big oil/coolant slick on the road...... luckily I didn't crash putting the tires thru the slick...... I was kind of crazy when I was younger about HP........well, i still am I guess...

I split a 835 lbs duramax block from neck to nuts. It lunched a bearing, didn't find the MASSIVE crack until I was cleaning the block. It was not on my list of things to replace. I invented new cuss words. I was couple miles short of blowing the crank out the bottom and driving over it.

 



Since then I've heard that early dmax blocks were poured in Germany and we're known to have issues....not sure if I believe that. I beat that motor. Built a new one and beat that one daily. Pay to play or whatever.
