The great 5.3l vs 6.0l swap debate.

[George C]

either choice will work well. my 5.3 was a runner in stock form. if i had known what i know today i would probably not of got my 6.0 and stayed with the 5.3.

from a performance point of view...the larger motor will always have more torque. the HP between the two will be close with the same mods.

Not really. A cammed full bolt on 5.3 will always put out less than the same setup on a 6.0 you could probably get another 50hp out of the extra cubes.
a 4.8 to 5.3 would be marginal, but noticeable. 5.3 to 6.0 would be night and day. As long as the 6.0 was healthy.

theres a few 5.3s making more power then 6.0s. its all in how the parts are chosen.
