If you're in the market for a serious upgrade to your ride, the Texas Speed & Performance 376 CID LT1 engine is worth a look. This isn’t just any engine; it’s a powerhouse built with care and precision. What’s great is that TSP is now offering a brand new engine block at no extra cost—no core fee or exchange needed. That’s a win right there.

When you get one of these 376 CID LT1 short-blocks, you’re getting some solid components straight out of the gate. You can choose between a Callies Magnum wet-sump or dry-sump crankshaft, depending on what suits your build best. The 6.125" H-Beam connecting rods come with ARP 2000 bolts, which means you’re looking at durability and strength. Plus, the proprietary forged pistons and rings from TSP/Mahle are designed to handle the heat and pressure of serious performance driving.

Now, if you want to customize your setup, TSP has got you covered. They offer a range of upgrades that you can check out in the drop-down menus. The standard setup uses a 4.070" bore piston set, but if you’ve got something specific in mind, just reach out. They’re open to custom builds and can help you figure out the best connecting rods and crankshafts for your needs.

One thing to keep in mind: the price you see doesn’t include shipping, as all engines ship via truck freight. If you’re ordering online, don’t be surprised when they reach out with the actual shipping cost after your order. And if you’re in a hurry, they offer an expedite service to get your engine built and ready to ship in as little as five business days, depending on parts availability.

Now, let’s talk about some of the features that make this engine a solid choice. All TSP Gen 5 LT1 engines come equipped with an ARP main stud kit. This is essential because GM had some issues with main caps shifting in the Gen 5 LT1 block, and TSP has taken steps to prevent that from being a problem for you. If you’re planning to ditch the AFM/DOD system, they’ll plug those stacks during machining for you. But if you want to keep that feature, just give them a heads-up.

And here’s a nice touch: every engine comes with 12 quarts of break-in oil at no extra cost. This isn’t just a gimmick; proper break-in oil is crucial for ensuring your engine’s rings seat correctly against the cylinder walls during startup. Most regular engine oils don’t have the right additives for a new engine, so TSP makes sure you’ve got what you need to start things off right. Once you’re past the break-in period, they recommend using Driven Racing oil—specifically the HR2 conventional non-synthetic—for optimal performance.
