All TSP 376 CID LT1 short-blocks will come standard with your choice of a Callies Magnum wet-sump or dry-sump crankshaft, Texas Speed & Performance 6.125" H-Beam connecting rods with ARP 2000 Bolts, and TSP/Mahle proprietary forged pistons and rings.

The build time will vary according to parts availability. Give us a call for more information!
All TSP gen 5 LT1 engines will come standard with an ARP main stud kit. GM has had problems with the main caps moving in the gen 5 LT1 block, so we require all of our gen 5 LT1 engines to get the ARP main stud kit to help alleviate any possible issues with this. Also, we will assume that you will be removing the AFM/DOD system with your engine. As such, we will automatically plug the AFM/DOD stacks in the valley of your block during the machining process. If you plan to retain the AFM/DOD feature, please let us know so we can modify your build appropriately.
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
Lethal Performance is proud to offer the entire line of products!
