HUG 408MAGSTROKERMIDB

MID COMP BALANCED ROTATING ASSEMBLY

MID COMPRESSION RATIO, CAST CRANK, I BEAM RODS, KB HYPER PISTONS

$1696.07

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.

This kit includes:
SCAT 9-360-4000-6123-2125 Cast Crankshaft
SCAT 2-ICR6123-2124-7/16 (I-Beam rods)
Keith Black Hypereutectic Pistons #KB416.030 (4.030")
Ring Set Sealed Power 2114+030 (5/64-5/64-3/16")
Rod Bearings CB481HN Clevite "H" series

Main Bearings MS1266HG Clevite "H" Series (Wide Flange 74-03 blocks)
Precision Race Balancing by Hughes Engines, inc.

Price does not include any heavy metal. This is added as needed on a case by case basis.
