Correct. What happened was, 'someone' took readily available forged domed 
pistons of the correct bore size and cut some or all the domes off to reduce 
compression for a street/track engine. But many domed pistons are forged with a 
'reverse dome' underneath for weight savings, so cutting the tops flat in these 
pistons leaves thin spots... which collapse under performance use. In the case 
of John Parson's first engine, he drove his Pantera to 'Vegas & then to the 
track with zero issues. During his event, he got 5 out of 8 laps completed 
before one or more of the thin piston domes caved in. He went back to L.A. on a 
rented trailer.

A question for Dan:
In one of the how-to-build stroker-Fords publications (which I can't find 
right now), I noticed a reference to a Federal-Mogul adapter main bearing set 
that supposedly fit the Windsor block journals but was made thicker to take the 
smaller Cleveland crank journals- essentially duplicating some of the SVO 
blocks with a cheap junkyard Windsor. I can't find any p/n for such a bearing in 
Federal-Mogul catalogues and since F-M were sold, their web site is useless, 
with no contact address. Ever run into such a bearing set? Seems like this would 
make building a budget stroker-Windsor a little simpler, if it existed.
