I ordered the Callies with my 402 along with a Callies crank. I have heard that they are both great pieces and can handle some serious power.
I'm sure all aftermarket pieces are a great upgrade over stock, but probably just personal preference on name brands...

It's between the Oliver Billet with ARP3.5 Rod Bolts and the Carrillo with SPS Carr bolts.
I'd probably lean ever so slightly toward the Carrillo rods, because they are H-Beam, but the Oliver Rods are NASCAR parts too and their parabolic beam is patented, so you can't go wrong with either one.
I have Oliver in my car, though, and I still can't vote for one over the other.
Nothing else on that list is even close in terms of quality or price.

Oliver has the EDM pin oiling at only $55 a rod.
Lentz is also very good, but you're looking at $3k+ for a set, and I'm not sure they are significantly better than an Oliver rod. A street engine or even drag engine will never see the sustained forces of a Cup engine, so I think a standard Oliver rod would take anything you could throw at it.

several turbo mustang guys in the 7's on eagle rods (even with standard bolts).
Ive seen BBC guys are in the 7's as well on them (and just longer which the longer they are the weaker I would say)

i know some guys who swap pistons and are cherry with the stockers but piece of mind is worth the $$$ when a new motor is a lot more expensive.

Another rod that is good is the Howards Racing Components Powder Forged connecting rods. The fracture cap technology helps the rod keep it's roundness. And the material it's made from is extremely tough.

I have used all the ones on your list in various builds and my vote would be for the Carrillo rods w/ the SPS CARR bolts.
As mentioned, there are some other manufacturers you might want to look into like Lentz, Howards, etc.
Another set of rods I have used with great results are the Manley Billets. I would use them over the Lunati Pro-Billets any day of the week.
I have never had a problem with an Eagle rods as well. Most of the time, they do require more machining out of the box before being ready for use. In the end, the money you do save on them initially is lost due to this compared to a rod that is ready for use.

The question to ask is: Which rod is the strongest for its weight? Also termed "Specific Strength." You can design a rod that is stronger than anything, but it's going to weigh a ton. I believe in paying the most for optimized products. All the manufacturers optimize to some degree, but it would be interesting to see a subjecting tensile and compressive test for all the the major designs. Even more interesting would be to determine which is the most capable at high rpm vs which rod is best for max cylinder pressure. I doubt they will be the same design. Fatigue is another issue to consider (how long will it hold together under repeated abuse). The rod that is strongest in a one-time compression test won't necessarily last the longest in an endurance competition. Just my $0.02. These are the question I would be most interested in having answered.

I find that odd that it is said Eagle rods you use need alot of machining. The last 10 shortblocks I've done for customers have only needed one set slightly machined at very little cost.
