6.0 swap need help! I just bought a 2000 6.0 for my 98 trans am. On the 1999-2000 6.0's the crankshaft sticks out the back like .400th of an inch and will not bolt up to my standard trans? Anyone make a flywheel thats dished out or that works with this swap? Thanks for any help!

Well the motor is paid for and ready to go in. so I just really want to make sure theres not something out there that would be easier than swapping out the crankshaft and there is no spacer.

Wow, a lot of misinformed responses. A quick search would have netted you the correct answer, but to clear the air with facts:
LQ4 and LQ9 are Gen3 engines, not Gen4 (like the LS2, LS3, L76), due to the location of the cam sensor and knock sensors.
LQ4 debuted in 1999
Displacement was/is 6.0L
1999-2000 had iron heads
1999-2000 had a crank adapter to mate the LQ4 with the 4L80 trans (not LS1 compatible)
Compression ratio was 9.5:1
Bloack was Iron
In 2001 the LQ9 was introduced
Both the LQ4 and LQ9 shared the iron block and new 317 heads (similar as the 243, but with larger 76cc chambers), hence both are 6.0L
The LQ9 had 10.4:1 compression ratio, versus the LQ4's 9.5:1
No longer did either 6.0L require the crank adapter for the trans, now works with LSx applications.
In 2004/5 6.0L recieved improved rod design
In 2005 the LS2 block was introduced
It is essentially the LQ9 with an aluminum block
LQ9 still offer with an iron block.
