Set of assembled big block mopar 400 cast aluminum 9:1 flat top 0.030" over pistons with standard mopar 1851535 "LY" rods at 6.768". The casting number for these mopar performance pistons are MP P4529427 (4.37" bore). 1.825" compression height. Can be used in a 440 bored 0.050" over with the right setup. These pistons are no longer sold. From what I have found they were originally offered to bump up the compression of the 72+ 400 B engines. Will sell for $375 obo shipped in the lower 48.
