Racing Use Only, Not Legal for Road Use
All Texas Speed & Performance 427/429 C.I.D. short-blocks use a new GM L92/LS3 aluminum block! The standard price includes a fully-assembled GM L92/LS3 short-block with your choice of 4.10" or 4.125" stroke crankshaft with a 24X or 58X reluctor wheel.
The standard price also includes your choice of Wiseco 4.07" +3cc dome, -11cc, -14cc, or -30cc dished piston set. All Wiseco pistons offered are built to accommodate LS1, LS2, LS6, L92, LS3, and most aftermarket cylinder heads and valve configuration.
Any TSP 429 L92/LS3 will use a 4.070" bore piston set 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. We do offer an optional conversion package that will include the LS2 timing cover with a camshaft position sensor, LS2 valley cover, LS2 lifter trays, LS2-specific 1x timing set, and plug-n-play harness extensions for the camshaft position and knock sensor harnesses. This will be required if you are installing the engine into an LS1 vehicle. 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!
All Wiseco pistons will use a 1.2mm/1.2mm/3.0mm ring pack with a steel top ring and Napier second ring. This will be the standard ring pack used with any of our Wiseco exclusive piston sets, and this ring pack will also be offered with any Wiseco off-the-shelf piston set. We do build many engines to keep in stock, and we do our best to offer a variety to suit everyone’s wants/needs. With that said, not all engines will be in stock. The average build time will normally take three to four weeks once all parts are at the machine shop. This is only an estimate since circumstances and wait times will vary. Please give us a call for an accurate, up-to-date time quote.
If you are planning to use a power-adder and exceed 12 psi of boost or a 200 HP shot of nitrous, we would recommend building a 4.00" stroke engine since it will allow for a thicker crown on the piston. All of our engines with Wiseco pistons will use a Napier second ring for maximum oil control. This is just another step that we take with all TSP short-blocks to ensure you get the best quality possible!
Our TSP 429 L92/LS3 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) Stage 2.5 LS6 Cylinder Heads with 2.02"/1.57" Stainless Steel Valves & PRC Dual Valve Spring Kit with Titanium Retainers
Your Choice of TSP Camshaft
LS2 or LS3-Specific Timing Set
Johnson 2110R Lifters
TSP Hardened Chromemoly Pushrods
GM Cylinder Head Bolts & GM MLS Head Gaskets
TSP Ported LS6 Oil Pump
Bolts, Gaskets, & Other GM Items Included: LS2 Lifter Trays with Bolts, Camshaft Retainer Plate with Bolts, Rear Main Seal Housing Gasket, Timing Cover Gasket, LS2 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. 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.
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. 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.
