However, don't let the price fool you as this short block is built to perform. \"Closed Deck\" refers to closing of the open spaces of the head gasket sealing face of the block. The process involves milling pockets in the block to accept press fit inserts precision machined from a cast aluminum material to closely match the expansion rate of the base block material. This deck design serves to reinforce the most highly stressed portion of the cylinder bore reducing distortion and the potential for cylinder cracking associated with extreme power outputs. It also helps to reduce head gasket failures by stabilizing the sealing surface under extreme conditions.\u003cbr\u003e\u003cbr\u003e\n\nThe rotating assembly starts with a salt bath nitride hardened crankshaft running in ACL tri-metal race-series main bearings and Calico-coated Clevite rod bearings. The connecting rods are precisely machined for RalliSpec using American 4340 forgings and an extremely high strength H-beam design. FEA-evaluated design features around the large and small ends ensure high rigidity with the lowest weight. A choice of either Manley Turbo Tuff in standard and high compression options or Cosworth standard compression boxed-strut piston designs are available. Manley 2618 Turbo Tuff pistons are an excellent option for extreme power drag racing applications while the Cosworth pistons offer lower noise, longer durability, and lighter weight for street performance, road racing, and other applications.\u003cbr\u003e\n\nEvery short block is professionally assembled in our dedicted engine building room by our in-house builder who has over 20 years of motorsport level Subaru engine experience and has built hundreds of Subaru high performance engines. Every short block is blueprinted to carefully designed specifications that balance extended service life with extreme power capabilities. Every dimension is logged and a build spec sheet is provided for reference. The block is assembled with all typical short block hardware, plugs, and oil separator plate.\u003cbr\u003e\u003cbr\u003e\n\nThe block is optionally available machined for either a 14\/12mm RCM head stud of 14\/14mm RCM Superstud for maximum head gasket sealing at elevated power outputs. Note that the price includes a complete set of head studs. 14\/12mm head studs use a 12mm head side thread which will fit through the factory head gasket and cylinder head holes although it is a very tight fit(modification may make assembly easier). 14\/14mm head studs require the cylinder head holes to be drilled oversize and the head gasket center holes modified (or use gaskets intended for 14mm head studs like the RCM ones we sell).\u003cbr\u003e\u003cbr\u003e\u003c!--split--\u003e\u003cstrong\u003eTaxes:\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSingapore and Malaysia: \u003c\/strong\u003eAll import taxes are included in our pricing.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eEuropean Tva, Iva: \u003c\/strong\u003eTaxes will be calculated during checkout at our company import rate.
