I know the best route to go is a 4l80e, but I already have the stall for the 4l60, and I don't want to worry about having to sell it and by another one. What year model 6.0L do I look for? Anything else to look for besides the year model?

 

01 and up 6.0 will bolt up to a 4L60E,the earlier years have a thicker crankshaft flange.

 

Thanks for the help as always Whitt.

 

Make sure it has the aluminum heads and you will be ok.
