Info on old TRW domed pistons

P4007042 are listed in old Mopar Performance catalogs as 360 - 11.5: compression ratio. For 4.030" bore (.030" Oversize) It's not noted, but it's for a stock 3.58" stroke. I don't have any anymore, but like actual TRW pistons, these are pretty heavy and will tax the block, crank & rods at very high rpm's. Modern, lighter forgings would be faster at any rpm.

lol S'cuder beat me to it while I was doing research.
