I don't have to have a 5.3, just would prefer a v8-4.8 would be fine. I am thinking the 4.3 v6 is a derivation of the old 350 based 4.3. That being a 90 deg bank angle would require split crank journals to be even firing. Structurally I never liked that arrangement but that dislike seems to be non-founded as I never heard of a 4.3 with a crank problem.
