what do i have to do to bolt a 6.0 to my 4l60e in my 1500??

measure how far the crank sticks out from the back of the engine on the 5.3 vs the 6.0L. The early 6.0s had a longer crankshaft and will not interchange with the 5.3 unless it has a removable spacer stuck to the back of the crank. Some say it exists on some engines but I've personally never seen one. If you put the 6L in there with the long crank you'll be forced to go ahead and swap to the 80e, too. You can use an older 60e with the 6L/long crank engine. The 6L flexplate that came with it that is flat will work with the factory starter from the 5.3.

ok. yes the flexplate will work but then the 60e torque converter wont bolt to it. so im gonna have to swap to the 80e now i guess. do you know if my transfercase will bolt to a 80e?? or if theres any way possible to get that motor to bolt to the 60e?? i dont think there is a spacer on my engine it looks like its the crank...
