Natural","description":"\u003cp\u003eS\u0026amp;S Superstock™ crankcases; made from 356-T6 aluminum; are much stronger than the OEM case. OEM cases can\/may break in high performance or even stock applications; like more than a few of us found out the hard way. These S\u0026amp;S Superstock™ cases can be used for both stock replacement and racing applications. Important to the engine builder are the substantial savings in labor when using S\u0026amp;S cases. These cases come ''set up'' with sprocket shaft Timken main bearing races and cam needle bearings installed and pinion shaft main bearing race pressed in and line-honed. Additional parts that are supplied include Timken sprocket shaft bearings; cylinder studs; nickel plated case bolts; crankcase fittings; oil pressure sensor; timing \u0026amp; magnetic crankcase drain plugs and a special S\u0026amp;S design alternator stator plug clamp screw. The flywheel scrapers are machined to match the original 8-1\/2\" diameter flywheels. S\u0026amp;S cases maximize crankcase oil scavenging efficiency by using a ''ported'' design breather passageway. S\u0026amp;S cases are clearanced up to and including 5\"; no additional clearancing for strokers will be necessary. S\u0026amp;S cases come complete with assembly instructions.   Note: For 84-E85 Evo Big Twin models you must use a L85-91 style cylinder head bolt kit. These can be ordered separately as MCS 505266 (Gardner-Westcott) or 989599 (Colony) in standard lengths only.  Note: The aluminum H-D oil pump; (26190-73) or the S\u0026amp;S oil pump; MCS 519923; can be used in 70-91 applications.
