Ouch

 

can't see in the pic did it mess the bore up bad? Might hone out and just throw new slugs in it.

 

**** man, that sucks. Time to go forge!

You broke that running just a hotcam and a 100 shot? Were you running out of injector? What did your A/F look like?

 

i think its because of the crane rocker arms. been reading that people had problems and started switching out to dual springs. when they came out there was nothing about that but now they say you should. oh well the price to pay to play. i was thinking forged but.. i plan on going with a 408 not sure though about the 402. and whats the benefits of going iron. i know iron is like 90lbs heavier but thats ok if the benefits are worth it.
oh yeah the wall has a pretty deep groove

 

I think it's in your tune. Half of your plugs look bad and then obviously the piston is screwed.

 

That must be my motor's twin brother
except that mine didn't want to be lonely #5 & # 7

 

it wasnt on a 100 shot anymore. was setup on a dual stage. the plugs are bad because i drove it home misfiring. i gather its a combination of my mishift prior and now it just gave up. prolly dropped a valve. but its cool gives me reason to change out the motor. i did not pull off the drive head yet but that one checked out of during the compression test.

 

I wonder where the piece of piston went.

Doesn't look like the bore is screwed up.

You might just replace the piston, depending on how cheap you are.

 

going with a fully built 402/408 and a procharger... in the works
