Yes! Rarely listed though since 360’s are not known for an .080 capable bore size. But KB will have these. It’s a simple call to tell them. If it needs to be a place to call up and get them, Hughes engines has them listed. I would myself not call this a custom piston. Perhaps
@RAMM might disagree, IDK?!?!
I also noticed shopping around that a standard bore 360 piston isn’t as prevalent as one might think. Though I’m sure there in or at the store/manufacturer’s shelf somewhere.
One of the cool things about most piston manufacturers, is they don’t consider a change a custom piston unless it’s after 1 or 2 changes. It depends on the piston manufacturer.
You can call them and say something like, on this here piston, I’d like deeper valve cuts for a mister lift cam I’m using. It has *** lift. And they’ll take a minute to cut the valves deeper for you.
Or thinner rings or a moved pin. But if you ask for more than what they say is their limit, 1, 2, or 3 changes, “Custom Piston” time! It’s a manufacturer call.
