I politely disagree with Barry R. |

I have in my current fleet four 427 FE's and a 428CJ. I have had several 390's in the past and a 352. These engines normally have never been decked or maybe .005 - .010. It is advantageous to leave the deck as tall as possible to maintain pushrod and intake manifold geometry. Budget rebuild shops typically turn out crap from my experience with AER and the like. I am not faulting the quality of the pistons, only the design which sucks big time.
A really good set of zero deck forged FE pistons costs about $500 plus shipping from Ross including pins. The pistons are right at 510 grams on a 427, less for a 390 or 428. That is about 250 grams per piston less than a TRW forged piston at least. I have not seen a weight of one of those cast pistons but predict it to be in the same ballpark.
A piston at zero deck provides more efficient combustion for less chamber area and obviously more power. There are different chamber size FE heads to vary compression by a couple points. Milling the crap out of a good FE block is wrong, it just sets up a whole bunch of labor and potential problems easily solved by getting the right pistons in the first place, thereby making heads and intakes usable on other engines in the future.
If you want even lower compression, dish pistons are available too.
