late model 6.0liter swap
Has anyone done a swap 0n an 03' "drive by wire" setup, I,ve got a 5.3l and want to go to a 6.0l, should just be plug and play with a re-flash of the pcm, also want to put a 5.3l in a truck that had a 4.3l which is an 05' silverado, any help would be great....

The 4.8 is plug and play also. It took a total of 5 hrs to have my 4.8 out and the 5.7 in and driving around. The tune isn't going to be that much off. My fuel curves were nearly perfect. That is because the 4.8, 5.3, 6.0 use the same intake and injectors. Injectors were the same part number on my 05 4.8 as they were on my buddies 03 6.0. The only thing different on the intakes are the top of them. They might be the same on the newer 6.0's but the intake that we had were diff. on the top, but identical on the inside. Also had both my 4.8 intake and the 6.0 flowed and they were identical. They flow just like a F.A.S.T. and at some rpm's better, but once you get above 6500 rpm's the F.A.S.T. keeps going up, while the truck intake levels out.
