[Fot] GT6 Connecting rods

[Brian Dennis]

It looks like bearing failure. Which then heated the rod to a nice molten orange along with the bolt stretching it to failure or pulling the treads from the rod. This happened to me in 2001 at Mount Washington hillclimb. My internal parts escaped with a very loud and dramatic noise just after the finish line. Lots of spectators to witness it. Also have the in car video. I thought it was a little down on power the top half of that run;) The branded scar from my end cap was still in the pavement when I was there in 2011.
As for suggestion, I would go .40 over since it will be need to be stripped down bare for inspection anyway.

I had a grenade go off in my engine at the last race. Not the stock rod failing, but it appears on first inspection that an ARP rod bolt gave it up. Some bad bad things happened after that with the piston destroyed, the crank gouged, and got only knows what else. The block and #3 cylinder wall doesn’t looked scarred but we’ll see if it survived when I have it magnafluxed. 
I knew when I turned the engine upside down on the engine stand and lots of metal noises resulted I was in trouble. Now its decision time on how to rebuild. 
Suggestions are welcome. Is this the time to go 40 over from 20 since new pistons are needed? I wanted a hotter cam for next season but not this way. The crank has serious gouges and I don’t know if its savable. That’s my wallet in the pic along with the other totally broken part.
