  • **Power Bore Sleeves are not available below 4.07" bore size** ​ All Texas Speed & Performance resleeved short-blocks use a NEW resleeved Gen 4 aluminum block with your choice of Power Bore or Darton dry sleeves! The standard price includes a fully-assembled short-block with a 3.622" stroke crankshaft with your choice of 24x or 58x reluctor wheel. All resleeved blocks are fully machined and assembled at our facility, and we use state-of-the-art Power Bore and Darton dry sleeves that have a much higher tensile strength than the standard GM sleeves. They are also much thicker than the sleeves used in GM blocks. We do not recommend running larger than a 4.125" bore size if you are using any type of power-adder. The standard price also includes your choice of Wiseco or CP Pistons in ranging in size from 3.903" to 4.185" bore sizes. All available bore sizes and piston volumes are listed in the corresponding drop-down menus. All piston sets listed are 2618 forgings and feature lowered ring lands to accommodate nitrous and boost applications, should the customer choose to use them. This engine selection is for all available engine builds using a 3.622" stroke crankshaft. Both 3.622" and 4.00" stroke applications are recommended if you plan on using any power-adders. We also offer 4.10" and 4.125" stroke applications, but we recommend those setups for naturally aspirated use only. Our TSP Darton sleeved long-block includes everything in our short-block package plus the following parts that are installed on the engine: Precision Race Components (PRC) 247cc Cathedral-Port Aftermarket Cylinder Heads with 2.12"/1.60" Stainless Steel Valves & PRC Dual Valve Spring Kit with Titanium Retainers Your Choice of TSP Camshaft LS2, LS3, or LS7-Specific Timing Set Johnson 2110R Lifters TSP Hardened Chromemoly Pushrods ARP Cylinder Head Bolts & GM MLS Head Gaskets Melling Oil Pump or GM Dry-Sump Oil Pump (C6 Z06, Grand Sport, & ZR1 Only!) Bolts, Gaskets, & Other GM Items Included: LS2/7 Lifter Trays with Bolts, Camshaft Retainer Plate with Bolts, Rear Main Seal Housing Gasket, Timing Cover Gasket, LS2/7 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 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. All of the PRC aftermarket casting cylinder heads already have the larger bolt holes to accommodate 1/2" head studs. The standard cylinder heads in the long-block assembly come with the PRC cathedral-port 247cc cylinder heads. This will be the option to choose if you are wanting to stay with a cathedral-port cylinder head and intake manifold design. The PRC LS7 cylinder heads will be a rectangular-port design that will require the LS7-specific intake manifold. If you would like to include rocker arms with your engine, be sure to select the appropriate set that corresponds with the cylinder heads you are ordering! The PRC 247cc cylinder heads will require an LS1-style rocker arm set, the PRC 260cc LS3 heads will require an LS3 rocker arm set, and the PRC LS7 cylinder heads will require an LS7-style rocker arm set. We have listed the GM rocker arm sets with bolts that includes the Comp Cams trunion upgrade kit. This is highly recommended since the factory rocker arms are known for losing needle bearings with aftermarket camshafts! When selecting your crankshaft, you will see options for a long-snout crankshaft for factory GM dry-sump oiling. This is what you will need if the engine is being installed in a 2006+ Corvette Z06, Grand Sport, or ZR1. When you select a dry-sump crankshaft, we will automatically make the appropriate changes to the remainder of your engine build. The dry-sump crankshaft cannot use a TSP ported LS6 oil pump, so we will install a new GM LS7-specific oil pump. It will also include other dry-sump-specific items, such as exhaust manifold gaskets, oil pan gasket, and balancer pulley bolt. A factory GM dry-sump block does NOT have a provision for an oil dipstick tube, so the block will not be tapped for one if you select a dry-sump crankshaft. 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! All TSP engines will include two oil changes worth of Driven Racing 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 Driven Racing 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! We also offer the Driven Racing oil for your new engine once your break-in is complete. We recommend using either the HR2 conventional non-synthetic or the LS30 full synthetic oil. Please note that the Driven Racing LS30 is the ONLY synthetic oil we recommend using in your engine because it retains the necessary ZDDP additives. ​ Bore & Stroke Combinations 3.903" Bore x 3.622" Stroke = 347 CID 4.005" Bore x 3.622" Stroke = 365 CID 4.01" Bore x 3.622" Stroke = 366 CID 4.03" Bore x 3.622" Stroke = 370 CID 4.07" Bore x 3.622" Stroke = 377 CID 4.100" Bore x 3.622" Stroke = 382 CID 4.125" Bore x 3.622" Stroke = 387 CID 4.155" Bore x 3.622" Stroke = 393 CID 4.185" Bore x 3.622" Stroke = 398 CID
