flywheel bolts Does anyone know which LSx engine installation has the longest bolts for the flywheel to the crankshaft? I have a crank out of a 6.0 from a Hummer that had a spacer on the rear that had to have used longer bolts than some of the others. I am doing a custom installation with a different transmission and need some longer bolts than the ones I have from a 5.3 that just has the flexplate on it. Thanks

Some of the truck cranks (your 6.0) were shorter and used a spacer w/ the flywheel. Other cranks (your 5.3) were longer and didn't need the spacer.
Try shopping for a late 90s 6.0 truck. If they're longer than your 5.3 bolts, there you go.

Im not sure about txcar but the bolts that I ordered with the spacer are 28mm long and the CTS-V bolts are 29mm. I need something in the 35-40mm range with my spacer and the flywheel. I was debating about getting a new flywheel if I can find the correct one for my app, or finding the correct M11x1.5 bolts which seem impossible. Ideas anyone? How about short full thread headbolts that I can cutdown?

The bolts are a M10-1.5X??
They sell them anywhere from 16mm-40mm and they are a lot cheaper than the dealer. They are class 10.9 bolts so strength won't be an issue.
The bolts for my ls1 are M10-1.5X40
