The crank and rods are the only thing the same assuming you throw in a new cam. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

 

Almost BigKid - you corrected the correct answer. <img border="0" title="" alt="[Embarrassed]" src="gr_emb.gif" />

The 5.3, 5.7, and 6.0 all have the 92 mm stroke. So they all have the same crank and rods. The 5.3 has a 96mm bore, the 5.7 has a 99mm bore, and the 6.0 has a 101mm bore.

The 4.8 has the same bore as the 5.3, but has a shorter stroke. It alone has a different crank and rod combo of these.

*the pre-01 6.0s had a slightly different crank and iron heads.

 

I thought the 5.3 and 5.7 shared the same stroke and the 5.7 and 6.0 shared the same bore? So the 6.0 and 5.3 would have a different bore and stroke?

*edit*
I corrected myself. 5.3/6.0 share a 92mm stroke and the5.7/6.0 share a 101.6 bore and no shareing between the 5.3/5.7.
