Default WTB: Forged 4" Stroke 2.250" Rod Journal Crank

Like the title says I am looking for a forged 4" stroke crank with 2.250" rod journals. 3.250" or 3.000" mains OK.

Let me know what you have.

Was there ever such a thing as a 4" crank. 3" mains and 2.25 RJ? This would be the ultimate crank for street 400's IMO.
