difference in 5.3 and 6.0(LQ4) intake?
Hey all-
I'm putting the '06 6.0 in today in place of the '99 5.3. The intake manifolds look the same so I was going to use the 5.3 intake since it has my return fuel rail and 42lb. injectors already in it.
My question is: Is the 6.0 intake better flowing than the old 5.3 intake or are they the same.
Thanks, TY
