What about the LML pistons/rod setup? cheap for new parts.

Everyone will probably jump my case, but the LML stuff seems to be a viable solution for the 650hp daily driver build. Look at the Fleece setup, or heck look at the abuse that Kory has put his LML through at above 700hp.

It wouldn't be a race setup by any means, but I personally would feel more comfortable taking a risk on the LML setup than going back in with the LBZ/LMM pistons if you are wanting a cheap alternative.

No facts, just an observation. :thumb: If it was already discussed, I'm sorry

Lml setup is still risky. If it were me I would throw a set of cut lb7 pistons on the stock lbz rods and call it a day.

Need to pull it apart and see if any others are starting to crack. Don't think you can slap lb7 slugs in because of the weight difference.

I think that's a rather astute observation Russ and not a bad idea...
You're implying pistons and rods when you're saying "set up" right? I caught that in the opening of your post...
What about balancing? The bob weight is different, isn't it?

X2 other than don't lml pistons have a different size wrist pin?

Pretty sure he meant pistons and rods...not sure if the cranks between the LML and. LBZ are different, but I don't think so?

Lml setup is still risky. If it were me I would throw a set of cut lb7 pistons on the stock lbz rods and call it a day.

But then I think I'd need to do a myriad of other things as well, and for now I like the idea of just slapping a piston in and dialing the tune back and just getting it running on the cheap and easy side of life

Good point(s)
Is there anything beyond an "eyeball" visual inspection I can do to ascertain weather or not the pistons are in good shape? Like any sort of magnification process?

Lml short block have it balance ed with your crank main studs and call it a day [r lbz rods and lb7 pistons.

I beat the shit outta my truck for 3 years and only bent one rod .010-.020" at 650-700 hp and a lot of 1/4 mile passes and sled pulls dd and street races ect I was never nice to it. Pistons have over 250k on them and still look perfect I have pics of them sitting in the old motor still was lmm rods and my lb7 pistons

If building the engine is still the game plan... Then fix this one as cheap as possible, replace the cracked piston... Save money for build or other life stuff. Turn tune down and drive the Mother f-er.

Pull the glow plugs eh? For a visual inspection, or to do a compression test?

Thanks for lookin out for me Albert! If it's a left ill definitely let ya know, but by left is that the odd or even bank?

I need to make some space that Ive gotten accustomed to having with the smaller vehicle in the garage and get the beast in there and start pluggin away at it :eek:

Drivers side. If the piston is cracked you will have all kinds of oil in that cylinder. You should be able to crank it over and it will slobber out the bad hole.
