Russ you really need to lay off the Juice while boosting man. I don't care how "Fun" it is. Too much carnage.

Machine shop said failure was due to "metal fatigue".

Kind of find it a weird place for it to break, the load it applied on the crank end. Its broken near the harmonic balancer. Was the factory damper still on the car?

It is an early CincySHO fiberglass Gen 1 Cowl hood. It's rare to find one.

Correct. I got it with the car from MikeD who got it from Toolman.
Stock harmonic balancer; get better spinup on the head unit!
That information is classified.

It's amazing that it didn't do more damage. Normally, unless you have the same pistons I do, the pistons will run into the valves.
The only other crank I know of letting go was do to high boost levels and bad race fuel. #1 cylinder decided to diesel its way along independently of the other 5.
How and when did it happen?

That's where they all go, mine and Tom Guagliardo's included. It's a weak point on the crank.
Have the replacement gas nitrided. Cryogenic treatment is not worth the cost for raw carbon steel.

Post convention thrashing, backing out of garage--low rpm, no load.

one of our first sho's did that.We bougt it from a guy that had put water in it the summer and I guess he fore got about it the water froze in the winter the thermostat cross over tube was cracked. put another one on. The engine sounded good for about a month or so and a strange echo when we would rev it, thought it was bearrings took it all apart and the crank was broke in half it still ran. Bought a crank kit in 2 months the same thing broke in the same spot. The machine shop we deal with took care of it got another crank and the same exact thing after a few months of driving but this time I new better to go back to the machine shop with another broken crank so I pulled the engine out and its sitting in our SHOshed

Nice job! I snapped a Lightning crank down the center, running a 300 shot on top of 26 psi of Whipple 
. Truck went 110 in the 1/8 though, before it went ****.

DAMN. Thats something. 110 in the 1/8th? Thats crazy...
Congrats on being the first ever snapped SHO crank. I've never seen it done before.
Ive seen those GM 3800 S/Ced engines snap cranks. But those motors are garbage.

i'm glad I had my crank in the turboSHO checked extensively for stress cracks or any weakspots... by driving it 219K before I boosted it lolz
