gmpartsdirect says the con rods are 80 bucks each, seems kinda high for a factory rod, maybe they are a forged piece like the crank, which is only 174 bucks. I sure wish they would release the price for the block, im starting to think that with these prices for this engine, that im going to build a 6.2 for my Sonoma GT instead of a reg LS2.
Id be willing ot bet that even though the L92 block is aluminum the fact that its not a corvette part will make it cheaper than the grand for the LS2 block.
I doubt that. They will probably be pretty much identical for the price of the block. This is all speculation though.
It was posted earlier in this thread, but il be nice and repost it
12584727
But still nothing comes up on gmpartsdirect hopefully well have some pricing info here real soon.
I was about to order my LS2 block next week, im sure glad i cam across this info here becaue 6.2 is always better than 6.0, especially with a factory forged crank for under 200 bucks!!!
Can somebody verify that 12582714 is indeed the correct part number for the L92 bare cylinder head. In some pics i have seen it shows the casting number on the corner of the head the last 4 to be 5364 and i just want to verify this info, why would they not have the right numbers on the heads??
Also, will the titanium con rods from the LS7 work in any other LSx motor??
Also ive noticed that nobody has listed the part numbers for the springs, retainers, locks, spring seats, seals or the pushrods, are these parts just the same ones used on the 243 LS2/LS6 heads?
Also, does anybody know if you can take this new 6.2 block and use LS2 cam and timing chain setup and build it without the whole VVT setup, that would be nice, but i dont think there is any aftermarket controllers out there that can control this stuff is there?? Id love to have the VVT and the DOD, but how practical is it when talking about a conversion to an older vehicle?

Should be able to use the corresponding 24x reluctor wheel and control it with an LS1 computer. Im going to figure out a way to do it. As for the LS2 timing chain setup I would imagine it would work as they are very similar asides from the 4.065" bore versus a 4.0" bore. The L-92 has provisions for the cam phaser, but I would imagine with the LS2 chain setup you could get around this and it would work okay.
Cool, thats what i was thinking, thanks for the help.
I have 2 more questions hopfully somebady cna answer.
Does the LS7 and this new L92 head use the same size valves on both the intake and exhaust? If so id be pretty sweet to be able to run the LS7 titanium valves in the much more affordable L92 head,
Also again does the LS7 titanium connecting rods have the same dimensions as the other LSx rod, they are just made out of a stronger and lighter material, becaue agian, if they interchange that would be a hot ticket to freeing up some rotating mass, and with the L92 rods going for 80.xx a piece and the LS7 rods going for 83.xx each well its pretty easy to see whih id rather run in my motor.

Thanks for the answers guys.
No. The LS7 intake is a 2.2 valve and the L-92 is a 2.16" valve. You could probably turn the LS7 valve down at a good machine shop though. The LS7 uses a 1.6" and the L-92 uses a 1.59" valve. You could easily have the exhaust side seat enlarged for the 1.6" valve.
As for the connecting rods, I dont know the lengths of the L-92. Hope this helps though.

Can the intake/exhaust rockers from the LS1 work for the L92 exhaust? I know the intake is offset, but if the LS1's rocker arm will work with the L-92, then that'll save about 130 dollars for heads assembled without springs, and would come to about 800 for both heads.
Also, what are the valves made out of? I can imagine they might be pretty heavy for higher-rpm usage...

Are we sure the crank is forged? (Sorry if that's been mentioned somewhere already.)

I wouldn't think a casting number would be a corresponding part number.

Will the L92 head fit in place of LS7 heads in a stock LS7? In other words will it bolt-up to the LS7 block and will all LS7 parts, including the intake manifold, bolt right up to it?
