USES A GEN III BLOCK
CLICK HERE TO READ ABOUT OUR ENGINE MACHINING FACILITY!
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.
All Wiseco 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, and CP Pistons will accommodate LS1, LS2, LS6, L92, and LS3 cylinder heads.
Any piston set will use a 4.03" bore piston, unless otherwise noted. Other custom build items are available. We also offer Callies and Lunati crankshafts, as well as Callies, Lunati, and Oliver connecting rods. 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!
Our TSP 370 C.I.D. long-block includes everything in our short-block package plus the following parts that are installed on the engine:
Precision Race Components (PRC) 225cc As-Cast Cathedral Port Cylinder Heads with TSP Dual Valve Spring Kit
Your Choice of TSP Camshaft
LS2-Specific Timing Set
Johnson 2110R Lifters
TSP Hardened Chromoly Pushrods
GM Cylinder Head Bolts & GM MLS Head Gaskets
GM High Performance Oil Pump
Bolts, Gaskets, & Other GM Items Included: GM Lifter Trays with Bolts, Camshaft Retainer Plate with Bolts, Rear Main Seal Housing Gasket, Timing Cover Gasket, GM Valley Cover Gasket, Oil Pump O-Ring, GM Balancer Pulley Bolt, Oil Pan Gasket, Water Pump Gaskets, Rear Main Seal, Front Crankshaft Seal, Cylinder Head Dowel Pins
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.
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.
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.
