I bought a 2002 6.0 long block.......i bought a 6.0 intake off of ebay......found some interesting things about the 6.0 fuel rails and the 4.8 fuel rails.....the 6.0 intake i got has only one fuel port for the fuel line......the other one goes to the front on the top side of the intake........on my 4.8....both the supply and return are on the LH fuel rail........can you swap the fuel rails and it run?

 

Some of the other rails are not return style rails. You can re-use your current rails and such.

 

good.....i was kinda worried......i have another question......can u use the 4L60E tranny on a 6.0?

 

Yep. It wont last, but yes it bolts up.

 

The 6.0 is virtually identical to the 4.8. Most everything will swap right over.

 

what about the flywheel......can u use the flywheel from the 4.8 on the 6.0

 

Youll wanna swap flywheels.

 

so get a 6.0 flywheel

 

No. Use your 4.8 flywheel.

 

so there's no difference in the balance of a 4.8 and 6.0
