  • All Texas Speed & Performance 347 CID short-blocks use your choice of a new GM 5.3L or LS6 aluminum block! The standard price includes a fully-assembled GM aluminum short-block with a factory GM 3.622" stroke crankshaft with your choice of 24X or 58X reluctor wheel. The GM 5.3L aluminum engine block is a very popular choice to use in 347, 383, and 395 CID applications due to its lower cost. It has excellent benefits, such as bay-to-bay breathing, that make it very durable to use in the build. For those customers that would rather use a new GM LS1 engine block, we do offer it for an additional cost. The standard price will also include your choice of Wiseco +12cc, -3.2cc, -11cc, or -25cc piston set or Diamond Racing -2cc flat-top or -8.6cc dished pistons. Any Wiseco piston set will use a 3.903" bore piston, and any Diamond Racing piston set will use a 3.905" bore piston. Custom builds are available. We offer multiple brands of connecting rods and crankshafts to suit any type of application. Every engine will come standard with the necessary oil and coolant plugs already installed in the block. Feel free to give us a call, and we will be more than happy to put an itemized estimate together for you! We also offer additional discounts if you pay via a cashier's check or wire transfer. All engines will ship via truck freight, so if are purchasing online the shipping costs listed will NOT be correct! We will contact you with a shipping cost after your order has been placed. All prices listed do not include the applicable shipping costs! All Wiseco pistons will use a 1.2mm/1.2mm/3.0mm ring pack with a steel top ring and Napier second ring. This will be the standard ring pack used with any of our Wiseco exclusive piston sets, and this ring pack will also be offered with any Wiseco off-the-shelf piston set. We have the Wiseco and Diamond Racing piston sets listed under separate categories since there are different ring sets offered for each piston manufacturer. All Wiseco piston sets will use the Wiseco/NPR-specific ring sets, and all Diamond Racing piston sets will use their gas nitrided ring set. We do build many engines to keep in stock, and we do our best to offer a variety to suit everyone’s wants/needs. With that said, not all engines will be in stock. The average build time will normally take 14 business days once all parts are at the machine shop. This is only an estimate since circumstances and wait times will vary. Our TSP 347 cid long-block includes everything in our short-block package plus the following parts that are installed on the engine: Precision Race Components (PRC) As-Cast 225cc Cylinder Heads w/ TSP Dual Spring Kit w/ PAC .660" Springs & Titanium Retainers Your Choice of TSP Camshaft Double-Roller Timing Set GM/Delphi LS7 Roller Lifter Set TSP Hardened Chromemoly Pushrods GM Cylinder Head Bolts & GM MLS Head Gaskets TSP Ported LS6 Oil Pump Bolts, Gaskets, & Other GM Items Included: LS1 Lifter Trays with Bolts, Camshaft Retainer Plate with Bolts, Rear Main Seal Housing Gasket, Timing Cover Gasket, LS1 Valley Cover Gasket, Oil Pump O-Ring, GM Balancer Pulley Bolt, Oil Pan Gasket, Water Pump Gaskets, Rear Main Seal, Front Crankshaft Seal, Cylinder Head Dowel Pins We also offer turn-key long-blocks that will include your choice of oil pan, intake manifold, throttle body, etc. We do offer many upgrades to customize your engine, such as ARP bolts and studs, Cometic head gaskets, etc. Please give us a call, and we will be happy to put an itemized estimate together for you. We also offer an expedite service to be able to have your engine built and ready to ship in as little as five business days! The build time will vary according to parts availability. Give us a call for more information! We do offer an upgrade to 1/2" head studs for those looking to run a large amount of nitrous or boost. The price listed for the 1/2" head stud upgrade will include the cost of the ARP hardware, as well as the necessary machine work. You must have an aftermarket PRC casting for 1/2" head studs! All of the PRC aftermarket casting cylinder heads already have the larger bolt holes to accommodate 1/2" head studs. The GM castings will not have the larger bolt holes, which would require additional machining. So, please make your cylinder head selection accordingly if you plan to upgrade to 1/2" head studs. All TSP engines will include 12 quarts of Joe Gibbs break-in oil for no additional cost. Proper break-in oil and procedures for your engine are just as important as the build process! The Joe Gibbs break-in oil allows for proper ring sealing against the cylinder walls upon start-up, as well as for the break-in period once the engine is up and running. Most off-the-shelf engine oils do not have the necessary ZDDP additives to allow for proper break-in of a new engine, and we want to take every precaution possible to ensure that your new TSP engine receives a proper break-in!
