As stated had my cylinder 6 piston crack on me. Was hoping to just be an injector but nope. Dropped the truck off tonight at a local diesel shop to see what they recommend on it. Wasn't planning on dropping big money on the motor but whats the best option? Could i just replace the single piston thats cracked and be on my way if it didn't do too much damage to the block?
LBZ: Need some advice (cracked piston)

A little more information would be helpful. Guessing the truck is an lbz? If so I'd get a set of lb7 pistons and main and head studs, key the crank and have it rebalanced. Then you'll have a nice little rebuilt motor.
Sorry, Yes the truck is an 07 LBZ...Built trans, 4094 turbo, air dog, etc...
Been thinking about it. Wouldn't mind just getting it back on the road cheap but also whats the best bang for your buck for a small budget build to make sure it can handle 650-700whp?

cheapest way to get back on the road is finding a good, used LMM/LBZ engine to drop in.
How much the piston messed up the cyl wall will determine if it needs a bore over or not. in the case of a bore over, it wont be a cheap build anymore

my buddy used a camera and said he saw the piston cracked...we will see hopefully tomorrow. maybe there will be some deals on black friday for motor parts:roflmao:
Sounds like what I went through last year. Mine burnt a hole in #8. I drove it home which hurt the cylinder. So I ended up boring .40 over and doing a full build. But now that's it's done, I don't honestly think I'd do it again. A good running short block is definitely probably gonna be your cheapest option.
I had the same thing happen, I bought a parts truck for the short block. Plan on doing head gaskets and studs then putting it in my truck.
I don't mind spending the money to start to build. But if i do...yeah the truck will never be fore sale lol....If i can find a lbz motor for around 3k i'll try to pick it up...But with my setup, more HP would be nice... Just wished i planned for the spending I'm about to do
Picking up a lbz long block for a decent price this week. Planning on swapping everything off my motor to this one. Anything you guys think i should do to the replacement motor while its out? Not looking to do a complete build but I'm open to any good ideas
Update:
Bought a 2nd motor and the short block is heading out the be bored .20 over and keyed cam and crank. Build plans are as follows
Carrillos rods
Finger oval pistons .20 over
ppe dual fueler
60 over lbz injectors
68 mm stg2r or 72mm danville turbo (undecidced)
Heads will get socal st 1 at least (good friends with the guy that owns the shop so I'm getting hooked up, nice to catch a break lol)
arp headstuds and main studs..
any other suggestions? Looking to go for 1k motor but be run around 750-800hp till i go with twins.

At 1000hp need billet mains or a girdle as well. If you go with a af cam buy a new crank as well.

What's the intended use for the truck?
I would do AF cam, new crank, don't waste $ on billet mains at that power IMO. Rest of your list looks fine. Run the Danville 72 for 750-800hp, spray it to 1000hp LOL

Inteded use for the truck is just a mess around toy. This isn't my daily by any means :thumb: Probably run it at the track 3-4 times a year otherwise it will be used for home depot runs. Hoping a single will make enough power for awhile till i get bored then twins will happen.
Who makes a decent crank for the $?
Keep reading on crank failures is the LML really gonna make a difference over my LBZ crank?
Block is going out this week to be bored 20 over and now its times to buy some pistons:woott:
Anyone have any experience with the Empire Stage 1 AF cam? Found one locally and thinking of picking it up.
