At this point it looks like about $3200.00. And you’ll make at or near 500hp falling out of bed. Fairly easy to do, and 500+tq.

Sign me up, just what Dr. Olds ordered.

Thanks so much for pulling this all together. You are making many dreams come true.

Newest update;
I finally got, what I now believe, is a more accurate shipping and handling cost.
Bad news, because of the current 25% tariff on goods in this category, the absolute best selling price possible will be in the $1800-1900 range. These will be better material than before, with some added features. But nonetheless, not an inexpensive piece by any stretch.
So, unless I get a host of additional interest, at this new estimated price, this project may be dead.
Let know your thoughts gentlemen. Thanks.

I'm still in.

Mr Nick

What is the difference between 5140 you mentioned in Oct, and the potential current 4340 material?

OLDSter Ralph

5150 has chrome
4340 has Nickel, chrome and molybdenum

I would think the 4340 would be a bit more tough and fatigue resistant.

It is. I toyed with the idea of going back to 5140 for these because the costs keep rising. And the 5140 is already way overkill, like the last shafts were.
But these will also serve well for the DX guys too so I guess it makes sense to just make em all out of 4340.
And these will be much lighter than any 3.00” main crank anyway, by a long shot.

Another update;
Ordered 2 as a sample. Unfortunately I didn't get the order in before their Chinese new year. So it'll be April or so before I get the sample cranks. From there it's 4-5 months.
Final configuration is, 4340 Billet, 4.00" stroke, Profiled counterweights, SBC rod journals, All else Olds dimensions. Final cost should be $1750.00 or so.

Thanks.
