An affordable quality H-beam rod and 440 6pak style flat top pistons for 440 Mopar.The rods should be stock size(.990 pin OK)6.76 length,3.75 stroke,pistons in +.020,.030.040 and .060 oversizes from 4.320 standard bore.




Sstock length would be 6.768 , that .008 makes a difference when the piston makers decided they needed to make a little shorter CH piston that'S ALREADY .020 in the hole on a factory blueprint deck , not that everyone has a factory blueprint deck .
