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!
 
2nd this, I am mostly in the same boat except I want to go stroker, have a block @ 3.995, same story with them being discontinued.
 
custom pistons from CP was not a big problem I did not order the it was Dan at DLS 15 years ago
 
DSS Racing or Diamond will make whatever you need, custom order. If you need tech help with the ordering, order through Full Throttle Speed.
