Return to Parts List Category : B- Small Block Dodge Magnum : Stroker Kits : 360 to 408 : Cst Crnk, I Beam rods & Hyper Pstns HUG 408MAGSTROKERMIDB MID COMP BALANCED ROTATING ASSEMBLY MID COMPRESSION RATIO, CAST CRANK, I BEAM RODS, KB HYPER PISTONS $2100.39 This is our mid compression stroker kit for the 360 block using the Keith Black Hypereutectic Piston and Cast Crankshaft. Magnum blocks tend to have a slightly shorter deck height than the older "LA" style blocks.  This particular piston has a 1.465" compression height and may come out of a Magnum block just slightly. If this happens on your application we suggest using a thicker head gasket to make up the difference.
