In production, probably 6 months or so from being ready. Contact Tom Molnar, I suspect that he ordered a few extras and see if you can reserve one.

I want to take off as much stress as I can so it lives a long happy life. The extra stroke isn’t needed.
Offset grinding a crank is what Stan is referring to. The maximum you can offset grind a 2.250 rod journal crank without welding the journals is .050; .040 to destroke and an additional .010 to ensure the rod journal is concentric. In your case it would be a case of the juice not being worth the squeeze.. Then again, you could always use a SBC rod journal or even a Honda rod journal size IF you wanted to use custom BBC connecting rods.

I emailed Molnar last week for an update and was told they estimate a completion date of January 2023.

I called Molnar yesterday for an update and spoke with Tom. He said to expect the cranks to be ready around August 2023.

That's typical for the World we live in today. I'm sure the powers that be are working aggressively to remedy the situation.

I haven’t received an email from Molnar yet. I just sent one asking for an update on the large main cranks

I have another email in to Molnar to confirm if the 3.25” main cranks are available. I have one on order with a deposit but they haven’t contacted me. They are listed on their website now.
