All Texas Speed & Performance 363 CID short-blocks use a new GM 5.3L aluminum block! The standard price includes a fully-assembled GM 5.3L short-block with a forged TSP 4.00" stroke crankshaft with your choice of 24X or 58X reluctor wheel. The GM 5.3L aluminum engine block is a very popular choice for trucks and retrofit vehicles, especially with power-adders. It has excellent benefits, such as bay-to-bay breathing and thick cylinder walls, that make it very durable to use in a build. You have the choice of a Wiseco -7cc or -15cc piston set. The -7cc piston set is a shelf part from Wiseco, but the -15cc piston set will be a special-order set. Typical piston build time is approximately four weeks before they are ready to ship to us. Other bore sizes are available on special request. Give us a call, and we can help you select the correct set for your application.

The Wiseco pistons listed will have a 3.80" bore size. 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 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!

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.

All TSP engines will include 12 quarts 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.
