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.
We also offer turn-key long-blocks that will include your choice of oil pan, intake manifold, throttle body, etc. We do offer many upgrades to customize your engine, such as ARP bolts and studs, Cometic head gaskets, etc. Please give us a call, and we will be happy to put an itemized estimate together for you.
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 a 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. <b>We also offer an expedited 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 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.
