Not every build gets an LS engine 👀

This project features a classic Oldsmobile big block, either a 455 or a 400 that has been stroked out.

This powerhouse is destined for a 1965 Cutlass 🔧

Are you team LS-swap or team period-correct?

The final pieces of the puzzle are coming together for this ’55 Chevy with a 1,000 HP Chevrolet Performance ZZ632.

Fresh tires just arrived: A massive pair of Pirelli P Zeros, measuring 14 ¼ inches wide.

Putting 1,000 horsepower and massive big-block torque to the pavement is no small task.

The real test comes next: seeing what kind of traction we get from the P Zeros 🛞

🛠️ We are in the final fabrication stages of this custom chassis for a 1950 Plymouth Suburban.

Key specs:

• Main Rails: 4-inch square tubing to minimize twisting.

• Power Capability: Designed for a small block Mopar, but fully Hellcat-ready.

• The Goal: Maximum performance for a unique, vintage wagon.

Looking for a chassis for your rare find? We’ve got you covered.

Fabrication update! 🔩

We are currently test-fitting our latest off-road chassis into this Ford F1.

To ensure it can handle terrain and torque of that John Deere Cummins turbo engine, we’ve engineered it with:

• Heavy-duty control arms
• High-articulation swivel joints
• Reinforced sway bar tubing

The goal? Maximum performance!

We just finished up the interior on this stunning Roadrunner! There is absolutely nothing better than a pistol-grip manual transmission paired with an old-school Hemi. ⚙️💪

Setting the new standard for performance. 🏎️💨

When you choose a Schwartz G-Machine chassis, our standard is what others consider an upgrade. We include high-end components as a baseline that you won’t find anywhere else.

Here is what defines the Schwartz standard:

• Precision Handling: Every chassis features a splined hollow tube sway bar equipped with billet end links and heim joint attachments—features often unavailable or only offered as expensive options by competitors.

• Superior Braking: Our baseline setup includes a 13-inch diameter brake system featuring beefy 6-piston Baer calipers branded with the Schwartz logo.

• Massive Power: While 13-inch brakes come standard, we offer 14-inch and 15-inch kits for those demanding even more stopping power.

Experience the difference of a chassis that comes loaded with “all the good stuff” right out of the gate.

Check out this second-gen F-body chassis headed to its new home.

At Schwartz Performance, we believe getting your chassis should be as smooth as the ride itself.

Here is how we do things differently:

• No Crating Fees: Say goodbye to those hidden $5,000–$8,000 crating charges.

• Door-to-Door Delivery: We ship directly to your house or shop via car transporter—no trips to a freight terminal required.

• Custom Rolling Solutions: We use specialized wooden wheels to ensure your chassis is fully rollable and easy to move the moment it arrives.

Simple, transparent, and delivered right to your door. That’s the Schwartz way.

Classic Muscle meets Modern Electric. ⚡️

We are giving this first-gen Firebird a whole new identity with a Tesla powertrain and a custom-engineered chassis.

Why go electric?

The answer is simple: because it’s exactly what our customer wanted.

We have also heard your comments about the track width. To make that wide Tesla track look right, we are going big with radical fender flares.

This allows us to keep a deep lip on the wheels while fitting everything perfectly under the body.

What do you think of this EV swap? innovation or sacrilege? Let us know in the comments! 👇
