99' crank= longer, spacer? for flexplate?
 

im in the middle of a build with a 99' 6.0 crank, is there a spacer or something that will let me keep my 03' 4l60e

If it has the long crank you CANNOT use a 60e behind it.

Edit: Possibly with a custom built converter.

+1 this man speaks the truth

o, i thought there was some sort of spacer that was made so you could use a 60e

No sir, the crankshaft flange is actually longer on the 99-00 6.0's, so you'd need the opposite of a spacer if there was such a thing lol

a grinder :D

what about any year 4l80e? the nv3500 5 speed? which years of these two will work?

Does the longer crank only come in the 99-00 6.0's? say a friend has a 99 with a 5.3.. will a 03 6.0 be a direct bolt on?

??????

The 03 crank should work with the 60E.
Any 4l80e 99+ will work with the LQ4 and the longer crank.
