After getting the bugs out of the fuel system, the testing progressed well and it was time for some 'real' laps. The third afternoon of tests ended in disaster. #3 rod decided to go elsewhere...I am not sure just what happened yet. I will do an autopsy when I get the motor in the shop. It appears, by looking in the hole, that a rod bolt broke and let the cap come up on one side and,,,it went down hill from there. The motor had about 3 hours running time on it and was making some serious power. 40-50 hot laps and we were all excited with the performance. Last edited by CHAPPER; 10/17/12 09:29 AM.

Whatever it is I hope you figure it out. Matt At this time, I am leaning toward a broken rod bolt. One bolt is a clean break, while the other one appears to have bent/broke. Also, enter into this mess, a blackened crank, that points to oil starvation. I am speculating that one bolt broke, allowed cap to start coming off and going out of round, which caused the excessive heat/blackening, the cap came clear off, piston stayed at top of cylinder and crank pin broke beam off..what ever happened, happened fast(7000+rpm) and the damage was severe. The other rods and bearings look good. I say 'good', in as good as could be expected with all the trash floating around in the oil and crankcase. 7423401-hemidamage010.jpg (114 downloads) If you like drag racing, support your local track.

I don't recall what rod bolt's were used. ARP #8740 bolts were used as that is the bolt supplied with them. Probably should have upgraded, but have used them without any problems in the past. I am still at a loss, as are others apparently, just where the oiling problem is. I would have to guess right now, that it is in the crankshaft. I KNOW all oil passages in block and crank were clean and clear upon assembly. All clearances were acceptable to my standards with previous motors. The 'previous motors' do NOT include a Gen 3 Hemi though. I can't imagine the clearances being hugely different on a Hemi versus a big or small block Chevy, small block Mopar, big block Mopar, etc. The blackened crank is what really makes me wonder just what is taking place in these motors at 7000+rpm.
