4.8, 5.3, LS1 Qs
I am getting a 4.8 long block for free and was wondering about a few things. What I was looking at doing is taking the crank out of my old LS1 and putting in in the 4.8. Should make it a 5.3, and make the compression ratio jump to 10.5 from the stock 9.5 roughly. Is this info correct?
So if that's the case, what is the difference between that and a factory 5.3? Cylinder heads or pistons, or both?
Also are any of the bolts in the bottom end torque to yeild? I know the head bolts are, but the rod and main bolts?
thanks guys.

you can not increase stroke on a bore that has miles on it bc it has some wear on the bore and when the ls1 crank makes the new pistons come down further its gonna hit the area that has no wear i know i am not good at explaining things
