ok, i have a 1999 silverado that had a 4.8 originally, I swapped in a 6.0 from a 2004 yukon. I used my original intake from the 4.8, but used the 6.0 injectors. Is there any differences in the 1999 4.8 intake to the 2004 6.0 intake itself performance wise? I used the original 4.8 intake so i could keep the EGR system in place. Wondering now if i shuld have used the 6.0 intake or if there is no performance differences..?

 

No significant differences other than the egr. Can't think of anything else.
