I have seen others post on here about the ridiculously long wait time on connecting rods, and I find myself in the same situation. I have had a set of Molnar 440 rods on order and the expected ship date just keeps getting pushed back, month after month. So I decide I need to just spend the money and order a nice set of rods only to realize there are not really any options. Here is what I discovered:
Callies Compstar: Forged overseas just like everyone else, but on "Callies owned" equipment, cost an extra $1K, and also not in stock/readily available Carillo: Only rods they list have a .927 pin and smaller journal sizes Oliver: Only rods they list are 7.100" long
My question is, does a high quality USA made 6.760", 2.375" journal, .990" pin connecting rod currently exist, and if so who makes them and where can I buy them? Or is this just a case that even if you are willing to pay up for a good set of rods, they just aren't out there? I just hate to miss a second full summer of having my car on the road waiting on rods if at all possible. Thank you for any input.

Sounds bad, but I'd thought about offering up the K1 rods I have on hand for my next build... but decided I need to hang on to them after hearing about what a nightmare it is now to find rods. With my luck I'd blow up the current engine and not be able to get another set to put my next one together.

Yes Tig you did get lucky as that is certainly a long time but not so much compared to what I and others are experiencing. Brad, it's funny you mention the K1 rods. I ordered the Molnar rods, and also a set of K1's from a different vendor figuring I'd use whatever set came in first and save the others for a future build. I realize all of the rods are originating from the same place overseas, but figured my place in line may be higher for one or the other of the orders and there may be a chance of getting one sooner than the other. Oh well, the wait continues. Brad, if by some chance you decide to sell your K1's I would be willing to pay over retail pricing for them. However I do understand your hesitance. As of right now I'm looking at is March 15 and even if they do show up on time, the engine builder usually runs 3-6 months out so when you factor that in it could very well be another lost summer.

Yes, Carrillo will make whatever you want. They have around a 15 week lead time. I have dozens of sets on order with them right now. It's the upgraded 7/16" CARR bolts that are taking forever to get from their supplier (ARP).

They dont have a 15 week lead time for the common folks. At least not this one. And yes it is a pretty common problem these days even worse for aluminum.

Considering most of the typically used rods are forged offshore, I think it comes down to who does the final machining... unless you're looking at $1500+ rod sets.
FWIW, I had a question for 440 Source today; I also happened to ask if their 6.76" x .990" ARP 2000 rods are in stock and they're available. I don't know about your (OP's) build and have no idea whether they're a suitable option or not.

Funny you mention weights... - I threw one of the K1s on my scale: 849 - I asked 440 Source how much theirs is in the same size: "about 860" - Can't measure the Eagles in my engine, but IIRC from the balance card they're 870+
I don't know if K1 has a different forging now to claim that much lighter

Why not support your local machine shop and resize a set of factory forged I-beams with new rod bolts? They aren't made of eggshells.
What did racers use before chinese h-beams became so common? It seems no one is interested in the I beams. I posted a brand new set of (12) Hemi forging rods that Direct Connection offered in the 70’s. Polished, shot peenwd, 1.09 pin, hard bolts. Not one reply. Of course that was before the shortages due to the China Bug. Still have them if anyone is interested. Going to post again, once I get a few pics.

The weights of the K1 (820) and Molnar (849) rods I got from the manufacturers. FWIW, I have a set of Molnar 7.100", 2.200" journal, Chevy pin (0.990') and width. Their web site says 832g, my set was 827g. And I looked at the weight on several boxes of the same part number and they were between 822-827g. So, the published "typical" weight of your part number might be different too. Each box was a matched set of the same weight.

What did racers use before chinese h-beams became so common? I’m sorry but this is hilarious. New rod bolts, resize rods, put bushings in the end. And you still have JUNK rods. Ya I did go 9.82 with them back in 1991 but they are still and always were junk.
