Description
All TSP 416 CID LT1 engines will come standard with your choice of a Texas Speed & Performance 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. We do offer upgrades, which can be found in the drop-down menus listed. Any TSP 416 LT1 will use a 4.070″ bore piston set, unless otherwise noted. Custom builds are available. We offer multiple brands of connecting rods and crankshafts to suit any type of application. 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 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.
Our TSP 416 CID LT1 long-block includes everything in our short-block package plus the following parts that are installed on the engine:
All TSP engines will include 12 quarts of 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 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 Driven Racing oil for your new engine once your break-in is complete. We recommend using the HR2 conventional non-synthetic.
