Is one year better then the other. I did alot of searches but never really found the answer. I found some cheap 4.8s by me with low miles but thought i would ask here first to see what year is better. thanks

found a decent price on some 4.8 2005 and up. Just worried about it being a 24 tooth wheel. I guess I could always take the crank sensor out and try to tell if its a 58 or not.

Well I'm about to be pushing a 2005 LM7 to its max with a PT7875 soon in my buddy's project car. We used ARP head studs, ARP 2000 rod bolts, LS9 head gaskets, a GT2-3 cam and Patriot dual springs. Motor is going into car this weekend and we are running E85. I'll update when we start tuning.

So do later engines really have better rods or heads or is there any real difference between different year 5.3s and 4.8s?
Is there any advantage to the later model 58 tooth setups when you're running a turbo?
Thanks

as far as the rods they look bigger, but i havnt really seen too much info that shows that the 05 up are really superior or more importantly that the 04 down are really weak. i bought a 2000 5.3 that im going push close to 600 horsepower and see if it lives.
