Look like they are still cast rods though. How much RPM are "upgraded" cast rods good for?
GX200 clone 18lb springs 1.3 ratio rockers?

I am not too sure which rods you are talking about, but billet rid are machines from a single block of metal, not cast. That is why they are so much stronger

The reason I asked for a brand is that most of the failed rods were on Predators. The coil bind issue was certain 18lb. springs on the hemi model.
Billet is not necessarily stronger than cast. It all has to do with what the alloy is and how the billet block was treated after it was cast. If it was rolled and heat treated then it will be stronger, otherwise it is still cast aluminum.
Forged would be the best. I haven't seen any forged rods yet on the aftermarkets.
Just trying to dispel some of the myths about billet vs cast.

I was under the impression billet rods were forged? CNC machined from a forged alum block, no?
I've read that billet blocks are often rolled or tempered after casting and that's the primary thing that makes billet aluminum parts stronger than just plain cast parts. I suppose you could consider rolling similar to forging since you're working the metal without it being molten. At some point it all starts off as a casting of some kind though. It's my understanding that in the end, it's the initial alloy and/or the tempering process that determines which is stronger.
As far as I know, billet is not cast
Have a look at this, it will clear up any misconceptions

All aluminum blocks start out as castings at some point. It's not like aluminum comes out of the Earth in big pieces and goes straight to a CNC shop. That's my only point to this.
Billet definitely has advantages like it says at that site, especially with being dimensionally more accurate since the shrinking stage was over before the machining. Hardness comes from the alloy and pre-working the metal after the billet block is formed. Billet blocks tend to have less inclusions and casting imperfections caused by sand debris and cooling issues, they still start off as molten aluminum poured into an ingot (mold).

... Or on the road...
(happened yesterday a few miles from here...)
Anyways.. proceed

Quick! Sid go grab some, might be able to make a few rods!
more than a mark I guess.. the road caught on flames...
Yes, it was kind of a "bring your own bucket" party.. luckily I wasn't invited
I mean 800°C (~1475 F) liquid alloy...
nothing I'd want to get in arms reach of tbh
Autobahn's locked down for the next couple of days, the new aluminium pavement isn't exactly well made so it needs to be removed again

That's because it was cast. They should have machined it out of a billet.
Dang! Look at that horse hanging over the cement guardrail. That must have been some crash!
