Hi guys, I search a lot and couldn't find too much infos about LR4 4.8 Forged, so I decide to post the infos about my engine.
I have a failure in my stock engine, from what I see the clearance between pistons and cylinders, so pistons and rods are gone...

I was lucky because my engine block is intact... or almost intact...
A oil galery was hit by the rod when broke, but my service shop fix this... I'll post some pictures next week about this... other problem that I find is that the crankshaft had a warpage, 0.002"... the service shop fix this without heat crankshaft... what you speccialist think?

here are the damages
oil gallery damaged


rod looks like was taken off the piston pin




well, after some searching and a lot of help of LS1Tech friends, like @svslow, @redtan and more, here are the parts that come to me today and I should assembly until the end of the month... (this week the service shop will bore the cylinder to the new measure
-Manley Rods ARP2000, 6.300": p/n: 14064R-8
-Wiseco Pistons: p/n: K474M965
-Wiseco Piston Rings: p/n: 3805HF
-Main Bearings King XP, p/n: MB5013XP
-Rod Bearings King XP, p/n: C807XPN
-Melling Oil Pump, p/n: 10296

So I will use my stock block and stock crankshaft and heads...

 

Sucks about the disaster, but those look like some quality replacement parts, sir. Staying tuned for updates.

 

I got a 4.8 with 132k miles, cross hatch on cylinder walls was still there and changed the head gaskets as they were just starting to leak oil into the bolt holes. I plan on throwing on a whipple till she blows. lol. Im gonna follow this so I know what to buy when she does!

 

nice! a whipple was one of my plans for this engine, but the price make me change to twin turbo.... I think your project will be great!

 

Thanks David! Next week parts will go to a speccialized company that balance the rotating and I hope until end of march have the car running...
the I should let the car with 600whp I think... don't want to have any more problems for at least 2 years lol
