Yes they are.
"The connecting rods for the two engines do provide us some visual identifiable differences. The 4.8L connecting rod is longer in length and has the casting number 121 with an additional boss on the thrust face. The 5.3L connecting rod is shorter with casting number 143 and no additional boss on the thrust face. Both connecting rods are PM (powder metal) with a "crack" parting face."
The 5.3 uses the same length rod as the 5.7 and 6.0. The 4.8 has it's own rods.

Its pretty obvious...you cant put a 5.3 crank in a 4.8 without changing either the rod length or the piston (with a different pin location)- otherwise you would have "NON-rotating assembly" when you bolt the heads back on-LOL-BJ
