TSP 370 C.I.D. LQ9 Short-Block - TSP-25-TSP370SB
All Texas Speed & Performance 370 C.I.D. LQ9 short-blocks use a new GM LQ9 6.0L iron block! The standard price includes a fully-assembled GM LQ9 short-block with a factory GM 3.622" stroke crankshaft with your choice of 24X or 58X reluctor wheel.
The standard price also includes your choice of Wiseco 4.03" +12cc, -3.2cc, -11cc, -25cc, Diamond Racing -2cc, -15cc, or CP Pistons -2cc piston sets. All Wiseco and CP pistons offered are built to accommodate LS1, LS2, LS6, L92, LS3, and most aftermarket cylinder heads and valve configuration. Diamond pistons are built to accomodate LS1, LS2, and LS6 cylinder heads.
Any piston set listed will use a 4.03" bore piston, unless otherwise noted. Custom builds are available. 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 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.
GM does offer a Gen III and Gen IV 6.0L iron block. The Gen III block will be similar to an LS1/LS6 block and will use all necessary LS1 covers, gaskets, and components. However, the Gen III block will use the LS2/LS3 cylinder head bolts. The Gen IV block will be an LS2/LS3 style block that will use the LS2/LS3 lifter trays, timing cover with cam position sensor, valley cover, etc. If you are installing the engine into an LS1/LS6-equipped vehicle, you will need to choose the Gen III block. If you are installing the engine into a 2005 or newer vehicle, you will need a Gen IV block. We also offer an expedite service to be able to have your engine built and ready to ship in as little as five business days! The build time will vary according to parts availability. Give us a call for more information!
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.
Lethal Performance is proud to offer the entire line of products!
