bore, stroke ?'s

Can someone tell me if the cranks are the same in all Gen III's and also bore sizes. I thought the 4.8 was different than the 5.3 and 5.7. Also is the 6.0 crank the same or different than the 5.3 or 5.7.
What about rod sizes. Same for 5.3 and 5.7?
Thanks for any info.

If thats the case, can you bore a 5.3 out to 6.0 specs? We have done 5.3 to 5.7, but nothing bigger.

I'm talking about the iron block 5.3; we bored it to 3.905. I didnt know how much bore it would take and if its the same as a 6.0 block, just smaller bore.
