Best rods?
What are the best rods for a SC motor? I want to keep the 5.7" length. Are the chevy 'pink' rods adequate? Block is bow-tie 4 bolt. Crank looks like its going to be a callies 4340 piece. Any help appreciated.

"Pink" rods are nothing more than select production rods that have been maganfluxed. The marking dye used in the magnafluxing process leaves a pinkish hue on the rods, hence the name.
Crower, Carillo, Oliver, etc make excellent qulaity forged rods which would compliment your Callies crank nicely. However, remember that rpm not boost breaks parts. Unless you're planning on spinning the engine hard on a regular basis, the "pink" rods would probably work fine for you. The higher cylinder pressure and compressive load on the bottom end rarely breaks parts in the absence of detonation, it's overloading and stretching the parts with inertial forces from high rpm and piston speeds.

Re: Best rods? (GRX)
I would not recommend the Chevy pink rods. They were used by Callaway in the original Twin Turbo motors and quite a few of them grenaded with a rod through the block. Probably due to lean detonation but they are the weak link none the less. It sure wasn't from high RPMs as the L98 TTs are pretty much all done by 5000rpms.
My car was one of these that broke a rod.... before I owned it. It now has a Callies crank and Carrillo rods. I think this is a great way to go.

Re: Best rods? (GRX)
Need to ask a couple of questions:
1) How much boost are you planning on running?
2) What pistons will you be using?
3) What CR will you have(kinda goes along with question #2)?
4) Most importantly, how much money do you have? :yesnod:
You can't go wrong with the aforementioned Oliver, Crower, Carrillo and even the Lunati rods(upper end) especially if they're billet rods. Expect to pay upwards to $1000-$1500 for a set(and that's not even mentioning titanium rods). In my opinion, if I was going to go over board on anything, it would be on the rods. That is where the majority of the money would go. Typically, when something breaks in the bottom end, it is usually a rod.
