Also instead of throwing all this money and time in parts regardless of what you're trading for you should probably just replace what you need to replace and save your money. You're not gonna be able to keep your foot out of it let's be honest here.
LBZ: Another broken piston. What's the cause ?
- Thread starter Dvierra86
- Start date
He's already running Lbz rods not a big advantage there only around 10% stronger then the Lb7/Lly rods. The Lbz rods even if switched to lml not a big gain and cost to work with Pistons.
Still the cost for the parts a 2nd time when it takes out everything you just replaced really sucks. You will be money ahead to get a single Lbz replacement piston and run it and save up money.
Your going to drop 2,150 then +60.00 Weight matching of all pistons within 0.5 grams which I would not do the machine shop can when weight matching everything to balance.
You would be into Lb7/Lly Pistons for 1050.00 plus the cost to delip them or race cast for the 1,600.00 area.
Overhaul gaskets, bearing set 800 area.
We over a few budget builds for about anyone. One of our best selling bundles is the Brian crower rod kit with race castvor upgrade to finger bowls all gaskets and bearings.

Also these refresh kits work great.

You are totally correct lol my foot is not going on a diet . Although it broke a piston not anything else so figure fix the weak lung and go again. I'm not gonna turn it up anymore than it is now if anything maybe turn it down a hair to help the trans life last a little long

The gaskets will be free beside heads. Those are like 40$ each my cost. And I'm in my trade about 1000$ and getting 2200$ pistons so I don't think I'm doing to bad on the deal. If I can sell more toys prior to rebuild then I might do rods might. But I don't foresee making anything over 600whp and be tuned by either atp or Ppei so i think the rods should be fine although I'm unfamiliar with the breaking/bending point it of the rods

Other then the overhaul gaskets calling off the self at Gm here's a lot of little ones at your Milage to replace.
I would be checking those Pistons out hard trade for 2,200 worth of Pistons. Also with Milage your at should be bored out to get the best ring seal.
I also work for General Motors myself.
Then put LB7 pistons in it and turn it down. Its just a truck. Things can get very spendy very quickly in this hobby.
Think about your priorities. Dont be stupid.
Amen to that Tom. Mine has been on tune 2 for a while now...no sense in blowing it up when the money isn't ad abundant as it once was

Oh I agree I usually keep it in 2-3 but every once in a while I like to hammer down haha.

I mean all the gm bulletins for oil consumption they say leave the bore alone and slap new pistons in it. Believe me I don't wanna do it more than once but I also don't ppm on turning it up anymore then it is now if anything load a 150hp tune and call it a day but still would like the fingers pistons as for a little more insurance knowing I can abuse it still with the 150 and won't pop a piston obviously as long as it's got a good tuner and keep the egts down.

Stop looking at the Gm bulletins I'm not telling you you should bore it out for oil consumption. Needs the bore freshened up from having 256k miles on it with a lot of heat and cylinder pressure. Does not matter what Pistons you put in it right now at all. Your next part to go will be the crank shaft or rods. There is not insurance when just slapping it back with what you think is the issue. While apart fix it right to save later or just replace with a replacement piston and run it and save and keep a roof above your family's head and food on the table.
X2^ if you're not building the motor, just replace the busted piston. Even if your cylinder wall is scuffed beyond what a light bone will remove, you will never notice the difference. Like I said, I'm all for building one Right, but from the sounds of it, you'd be better off just replacing the shot piston and slapping it back together.
I just can't see myself putting that much labor into the engine and putting a stock piston back in it to break another one. I would love to do aftermarket rods but then the crank is weak and thenneed a more crank and by then your talking 6-8k I'm parts. I'm basically getting the fingers pistons for about 800$ so can't really say no to that deal. And I just did new c headgaskets and arp studs about 4500 miles ago and cylinders all looked like

Just buy LB7, I'd rather buy injectors than build engines . LBZ not sure why everyone praises them , they aren't special.
I would trade my LB7 for an LBZ in an instant...........and I love my LB7. The O/P's problem could be easily remedied for under $2000. I would take that before 2 sets of injectors.
Just dont tell BBT I said that. She might get angry with me.

Go to a reputable auto recycler find a stock 150000mi eng with 30 day warranty,can your tuner ,drive to work. Very sorry to see what happened ,there is one thing you should know about this building truck stuff there are about three types of people that do it ,one is the person that is well off two is the person that dose it as a tax write off , three the single person with no children to support, that spends every dime on the truck. O the crazy person that dosent care about there family, you are not one of those! GOOD LUCK!
Yep, its retarded to go for broke building one if you don't have the cash.
Even more dumb to half ass build one.
Slap a junk yard motor in it and run it or sell it.
When mine blows up I'll buy a new truck and then this one will be the built toy, that way I'm not rushing like I did my last one and end up with less than I wanted.
