Okay guys I was finishing up my rebuild I have done over the past month and when I went to start it I had problems. At first the car would act like it had no spark plugs and never really start up.
Then It started to do this...


I figured something is wrong and pulled my heads and this is what I found...



and...



I thought I had my timing perfect...




The specs on the cam are 221/221 .558/.558 116 lsa Lunati Pn 55099
and I even had stock rocker arms and pushrods in for the startup.
Is my block fixable after the crack in the water jacket? WTF do I do?

 

OMG, thats bad man. any idea what happened? sorry to see that

 

looks like a valve spring keeper came out and dropped a valve. timing marks are lined up, what else could have happened

 

That block will make a nice paper weight.

 

Darton has sleeves that might fix it. But for the price of the sleeves and machining, how far would you be from just getting a new 402 or another LS1?

Plus a new motor could come with a warranty...

 

Did I do anything wrong?

 

Yes, lol
Isn't there two differnt marks on the gear for the double roller chain?
Is there damage in every cylinder?

 

wow I dont know you could re-sleave it but you would spend as much as a new motor might as well go with a new motor

 

No there isnt damage and there arent 2 marks the damage is only to like 3 of the pistons.
Only 1 needs to be resleeved... but I think there is a crack in the block by the water jacket.

Also one of the bad ports on the drside head there is a crack on the wall between it and the water jacket... I think the heads were bad.

 

Bad heads don't cause valves to hit pistons. This has happened before with doulble rollers not being set up properly. I don't know the details, b/c I've never personally dealt with one.

 

how could you set it up wrong there is a key to help you... You just line up the dots.

 

Ouch that sucks. There is 3 different key ways on a double roller, I forget the exact directions, but there is a specific way to line everything up..

You can get a brand new LS6 block from Texas speed for $599. Would be cheaper than fixing that block..

 

Is it even possible to fix the water jacket?

 

you would have to ship it off to some one who has experience resleving and have it resleved. Very expensive...

 

There is also a crack in the water jacket... huh

 

Yeah, trash the block and start over...

 

What is the best way to do this?

When I pull outh the engine should I pull the trans with it, and what is the easiest/cheapest way to get a block... maybe its time to get my stroker setup... can I use my block still if I go a bigger bore?

 

Use a lift and unbolt the cradle/engine/tranny then lift the car from the motor assembly.

 

what should I do with the block

 

sell it to a scrap yard... aluminum will get you at least some money
