TSP 376 CID Sleeved Gen 5 LT1/LT4 Long-Block, Stock Stroke
Racing Use Only, Not Legal for Road Use
All Texas Speed & Performance resleeved short-blocks use a NEW resleeved Gen 5 aluminum block with your choice of Power Bore or Darton dry sleeves! All resleeved blocks are fully machined and assembled at our facility, and we use state-of-the-art 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 Mahle pistons. All of the bore sizes listed include their shelf-stock piston sets, but larger bore sizes are available from Wiseco for an additional cost. Any of the listed Wiseco pistons can be built for a different bore size using any of the volumes listed for an additional $75. Please note that the typical piston build time is three to four weeks for non-stocking items, so we will not be able to start your engine build until the pistons are received. Full custom pistons with different volumes and bore size will be additional, so please give us a call for a quote. 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.
We offer multiple brands of connecting rods and crankshafts to suit any 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 you 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 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.
