Aftermarket pistons for over .060 over

I am thinking about going over the 0.060" overbore on the 308 I am rebuilding.  What pistons has anyone used for this type of install?  Dale Cooper only stocks up to 60 over.

    Dave Kostansek at one time was selling standard bore IH truck engine pistons that were .060" over the Hornet bore. An oversize in those pistons may be what you are after. From memory the IH engine was a 392 V8 but I won't take bets on that.

    IH  304 or 345 pistons have a standard bore of 3.875" Must compare the pin height for compatibility with the 308 rods and block. You want the flat top variety, not the contoured.

    I remember a guy running a stock car way back with a Hornet Engine that said he was using 55-56 Pontiac pistons in it.?  He and the car are both long gone now.
