GEN III BLOCKS ONLY
CLICK HERE TO READ ABOUT OUR ENGINE MACHINING FACILITY!
All Texas Speed & Performance 408 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 4.00" stroke crankshaft with your choice of 24X or 58X reluctor wheel.
The standard price also includes your choice of Wiseco, CP Pistons, Diamond Racing, or Mahle pistons. All pistons will use a 2618 forging and feature their proprietary ring pack. All pistons listed will use a 4.03" bore size 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.
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. You MUST select a set of PRC aftermarket casting cylinder heads for this upgrade! All of the PRC aftermarket casting cylinder heads already have the larger bolt holes to accommodate 1/2" head studs. The GM castings will not have the larger bolt holes, which would require additional machining. So, please make your cylinder head selection accordingly if you plan to upgrade to 1/2" head studs.
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. 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 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!
