Custom 360 Cranks?
Not a lot of options out there. I think there is one you forgot and I’m not going to remember it.
Thinking of it, Crower does billet cranks and IIRC Scat offers them to.
Moldex is worth calling. I think they are still in business.
I’ve been trying to convince Scat since about 2001 to offer 8 CW forged cranks.
Their answer was we won’t sell enough of them to make it worth doing.
And that problem lies engine builders and YouTube influencers not educating their customers on the benefits of 8 counterweights.
They ALL should have 8 counterweights but the bean counters won that argument a long time ago.
