So is the streched rod the problem?
Let us play, "Name that internal failure!"

BEATNGU, the head isn't off yet 
... that'll happen Monday.
DSF simply pulled the motor & put it on a stand. We only see evidence of some very fine metal in the oil pan but everything else appears to be fine from underneath...

STEEL RODS DO NOT STRECH!!!! at 7000 rpm.....
But valves will float and bearings will spin.
You people on these boards are amazing with the B.S. you preach ,no body looks at the whole picture about what Colman was doing, Beating his car up on a road course. NOW when he got his tune from whoever, they set it up for the rollers just like everyone does. problem is that he races it in extream conditons with PUMP gas. As that KB get hotter the chances for DETONATION drasticly increase. I am not going to carry on, I have offered to help Coleman and will if he calls.
There are limits that you can achive with pump gas and a blower. dyno is one thing but a road course is another...

update, #2, #3, & #6 pistons "slapped" the heads.
#6's piston broke up & bent the valves.
so, what caused that? ... if the rods didn't stretch.
also said that top of pistons show evidence of running a little lean... metled was mentioned.
might these heads be re-usable?
i'll post pics as soon as i can.

Livernois Motorsports, DSS, Keith Craft, VT or JDM, have one of them rebuild you a stock shortblock with maybe upgraded pistons. You may need new heads too. You already invested in a screw blower (read: massive torque) so you don't need extra cubes. Hopefully you don't need new heads but if you do I hear they are about $700/each. Show pics of the heads, we may be able to tell you if they can be salvaged.
If the rod bearings are bad you'll get excessive clearence and if they're bad enough they can hammer the big end of the rod egg shaped and also knock the crank journal undersize enough that it will allow the piston to travel further up the bore and hit the head.

if it were "bad rod bearings", do you mean factory bad or what?
correct me if i'm wrong, but that doesn't look too bad ... :lol1:
but i have no idea what i'm talking about :cryying:
i envisioned something much worse :chicken: ... where did the chicken go? :smmon:

You win Coleman...yours looks much worse than mine. :rockon:
that must be #6 ... where did the chunk go? down to the oil pan? out the exhaust? it couldn't have gone too far with my cats.
:lol: ... do i get charged by the laugh? ... :lol1:
oh, it hurts...
it [is] cost[ing] me a lot to beat you ... :loser:
most likely banged around the combustion chamber untill it went out the exhaust manifold....
