I have read it was an old school trick, before forged 460 pistons where common. You have to machine the top off quite a bit for them to work with the longer stroke. Then you have to more than likely do something with the valve reliefs. Not really worth the trouble anymore.

The piston would have to have .130 cut off of the top as the difference in stroke is .260. ( 3.85vs 3.59) . Since the piston is a dish design , there should be enough material to do that.

It seems like a pretty good trick for back in the day when 429CJ's SCJ's and PI's with forged pistons where plentiful along with 460 cranks. Like Paul said you can get zero deck height at around .1" without decking the block. It will also lighten the heavy TRW's. This was before everyone was spraying nitrous and the raised ring lands were not a problem, and forged pistons where $400.00 dollars in old money.

Randy Malik has a pretty good deal on Autotec forged pistons.
