RE: federal-mogul pistons? has anyone used them?

Folks,
I work at Federal-Mogul so I have to respond.

1) I have the same or better CNC equipment than any other piston manufacturer in the country. I have design equipment that they can't touch (paid for thru O.E. research). My stuff costs less because I make a lot of them - - remember high school economics?

2) It is not all all unusual to deck a block to achieve a desired compression ratio or deck clearance. Actually it's preferable. This way you decide what compression ratio and deck clearance to run - - instead of counting on tolerance stack up.

3) The amount of optional decking - even if .030 or .040 - - is really nothing when you consider that the decks are anywhere from 1/2 up to one inch thick on most engines. The engines we are working on are at least 30 or even 40 years old, and many have been rebuilt (and decked) numerous times. If we made the pistons at the original compression distance they'd be sticking up in the breeze on some of these blocks.

4) The raciest $800 small block Chevy pistons on earth are shorter than the original distance for the same reason. This way you determine the specs you want.
This thread, so far...
