4.1 4" bore forged piston options

[MNcarbturbo]

I've got a stock bore 4.1 block id like to drop a set of forged pistons into.

Full Throttle had a set posted for stock stroke 4" bore but I reached out to check stock status and they are discontinued.

Any other suppliers or anyone have a batch # for a 4" bore stock stroke forged piston?

I'm open to go 3.975-3.995 but I know ring packages get poor in this range.

Thanks!
