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 376 CID LT1 long-block includes everything in our short-block package plus the following parts that are installed on the engine:

Precision Race Components (PRC) CNC-Ported GM LT1 Cylinder Heads with PRC EHT .675" Dual Valve Spring Kit

Your Choice of TSP LT1 VVT Camshaft

New GM Timing Set

Johnson 2110R Lifters

TSP Hardened Chromoly Pushrods

GM Cylinder Head Bolts & GM MLS Head Gaskets

New GM Wet Sump or Dry Sump Oil Pump

AFM/DOD Stacks Plugged

Other Items Included: Lifter Trays with Bolts, Camshaft Retainer Plate with Bolts, GM Balancer Bolt, & Cylinder Head Dowel Pins

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.

***Shipping on motors is the only thing we don’t ship for free. Shipping cost will be calculated after the order is placed and sent in a separate invoice***
