On my 04 (LB7) I've been running around a 500hp tune since 06 and the head gaskets finaly give up, upper hose stays hard all the time now. I know I'm for sure going to do head gaskets and studs so heres the deal if I do it the right way the whole motor has to come apart to have it powerhoned with studs/deck plate. Now is there going to be to much material takin from the bores to use my stock pistons?

Now I know people have just put the studs in and called it a day with no problems, there is a huge price savings doing it this way since you don't have to buy all new torque to yeild fasteners/machine work :mad:

So if I take it all the way apart to do the studs the proper way do I just stick the lower mileage set of LBZ rods I have laying around in it and call it a day? But what a about needing to be rebalanced, here goes the correct way of doing things again? So if I'm going the have the damn thing rebalanced might as well get some Carrillo's for it right?

This truck is a driver not a racer but I don't need it as a daily driver either, it only has a SC4 trans, lift pump, 4"exh, and still stock turbo. I'm planning on doing a S475/stock twin setup to clean up the smoke a little and to add a little more fun to it, performance wise it's behind the times a little :D

So if I spent all the money doing things right machine work/balancing, studs, Carillo rods, and keying cams/cranks ect....Now I have a excuse to put bigger twins and dual fueler's on it just to flog the piss out of it now :woott: then it's probably just going to crack a piston :mad:.

Now for the pistons mine have about 65k miles, is there really any benefit to having them delipped seams they break either way anyways and theres really no other benefit for longevity using anything else on the street is there?

I'm not in a hurry to fix it just can't decide what to do if I stick the LBZ rods in it I have a reason to hold back, the big power is fun but I'm sure I will be building a motor more than once if I decide to go that route and just can't justify doing it a couple of times after just cracking pistons or breaking cranks.

The bigger twin kits are better in every way other than cost , even if you run them at 700hp , running mid 11's and being under 1400 deg is pretty wicked :D

Some truck have been running over three years with delipped pistons , other much less , remember you only here about failures not success story's , If your staying under 900 ho delipped cast pistons hold up pretty well IMOP

Now for the pistons mine have about 65k miles, is there really any benefit to having them delipped seams they break either way anyways and theres really no other benefit for longevity using anything else on the street is there?

there is some debate but i still believe delipping is better than not if its done right , remember people starting delipping pistons after a lot of cracked stock pistons in the old days, I have seen more stock non delipped pistons crack than delipped ones

I'm not in a hurry to fix it just can't decide what to do if I stick the LBZ rods in it I have a reason to hold back, the big power is fun but I'm sure I will be building a motor more than once if I decide to go that route and just can't justify doing it a couple of times after just cracking pistons or breaking cranks.

IMOP either build the short block with proper rods and pistons or leave it stock and throw some head studs on it , to do it right with all the proper machine work it lays out like this .

15%-20% stronger than stock engine ( 700hp ) cost is going to be 5k ( guess )

$7-8k ( higher if you want to get crazy but.... ) gets you a motor than can handle 700 for many years or 1k hp in spurts

Thanks for the reply Trent, whats the name of that machine shop in SLC you and :happy2::happy2: use? :D Think I will start checking on machine work cost are they capable of doing all work in house or is some of it farmed out such as balancing? Now days if a shop doesn't have a nice powerhone machine and doin that crap by hand with any old drill I turn and walk the other way or the shit heads trying to surface heads/blocks with a regular ol fly cutting bit,doing the feed by hand, and using a old bridgeport, this has actualy happend to me :mad: shit was ruined :mad::mad::mad:

Not worth pulling it apart just to install head studs. And if your going to the trouble of gaskets bearing and balancing I would step up to Carrillos. Your only out the extra for the rods since your already buying all the other parts and balancing anyways. We have core motors or we can use your motor. I can price you out a build the way you want it to be if we use your motor we can have your pistons checked. If there good and the bore is good we can have your pistons cut and coated. Just let me know if you would like some prices and our one shop is local to you.

Give me a call I will put you to work.Got alot of work going on.
I still get good pricing on machine work through Industrial so we can talk about that to.
