I need a 05 up, or LQ9 crankshaft. It needs to be from an engine with the LS2 style rods. Thank's J

 

Is there a difference in the newer cranks vs. the older?

 

The balance is different. If you run the hevier ls2 rods, and newer style pistons with the older pre 05 lq4 crank you will have to add heavy metal to balance.

 

good info.... i was under the impressive that the only difference was the 05+LQ4's have the beefier rods....

 

I have an 02 crank, if you can't find what you are looking for and you're in CA let me know.

 

You are correct, but the beefier rods weigh more so the bodweight on the 05 up, or LQ9 crank is hevier, or drilled less. The ls2/ lq9 style rods weigh ~30 grams more than the earlier style, and the pistons are another ~20g. So the earlier crank would need mallory added to the counter weights to balance with the hevier pistons, and rods.

Im back here in Co now. I might need that crank down the road, I will let you know.

 

I have a crank out of an 08 LY6, 6.0L. Will that work or is that too new?

 

Too new, different reluctor.

 

\Mallory is exspensive **** huh.I bought a china crank once for a 383 I put together had to add mallory to balance.Wound up almost spending as much for a forged piece.I think it was $75 oz. and I didn't even get high.

 

I have a 04 lq4 crank, $80 obo plus shipping
