273 forged pistons

My machinist called and told me he couldn't get pistons for the 273 that he is rebuilding for me. I solved the first part without too much effort and found cast pistons at Kanter and PAW.

I was wondering if anyone knows of a supplier of hypereutectic or forged pistons for a 273 either +.030 or .040. I'd like to run this pretty hard and I don't want to start off a new rebuild melting a piston if I don't have too.

Thanks
