§ 01

THE BRIEF

This 1993 Chevrolet 454 SS arrived as a solid starting point for a complete reimagining. The goal is to keep the clean, factory-white SS silhouette intact while rewriting everything underneath and under the hood. A Roadster Shop Low Pro chassis sets the stance, a Don Hardy supercharged LS makes north of 900 horsepower, and a Bowler 8HP70 transmission puts it to the ground. Inside, Dakota Digital RTX gauges, a fresh LMC dash, and Classic Auto Air keep the cabin as current as the drivetrain. Every detail — from the Johnsons radiator to the air ride suspension and subtle body mods — is being handled in-house.

§ 02 — Note from the shop

"Nineties truck attitude with a thousand-horsepower secret. Subtle on the outside, serious everywhere else."

CHASSIS MILESTONE

The Roadster Shop "Low Pro" chassis has arrived

The Roadster Shop "Low Pro" chassis has arrived! This is always an exciting day. It's like opening a long awaited Christmas present. If you are unaware, a custom part like this typically takes around 6 months to get. So if you are wanting to get a build started with us, the chassis is the foundational component that we will need to get coming asap. Send us an email and let's discuss your build.

POWERTRAIN MILESTONE

The 930 HP Don Hardy LS has arrived

The 930 HP Don Hardy LS with the 2.9L Whipple supercharger has arrived! The engine has been powder coated in custom picked colors. This setup starts as a 427 — better for boost than a 454LSX. When topped with the 2.9L Whipple, it's a screamer! Wait till we pair this with the 8HP transmission from Bowler Performance.
