1970 Oldsmobile Cutlass

1970 Oldsmobile Cutlass Rallye 350 — one-owner frame-off build with modern LS3 power and true daily drivability.
This 1970 Oldsmobile Cutlass Rallye 350 is a beautifully executed restomod that perfectly captures the spirit of classic American muscle while delivering the reliability and drivability of a modern performance car. What makes this example even more special is its history — this is a true one-owner vehicle, restored by the original owner after retirement and thoughtfully built to be driven and enjoyed.
The car underwent a full frame-off restoration, with virtually every component replaced or restored using brand new parts throughout the build. No shortcuts were taken, and the level of detail and craftsmanship is evident everywhere you look. Extensive paperwork and documentation accompany the car, outlining every aspect of the restoration while also preserving the history behind this special build.
Under the hood sits a GM Performance LS3 crate engine, delivering modern V8 reliability and strong, responsive power. Known as one of GM’s most respected crate motors, the LS3 features a lightweight aluminum design and produces approximately 430 horsepower and 425 lb-ft of torque, offering effortless performance with modern fuel injection technology.
Backing the LS3 is a 5-speed manual transmission, giving the car a true driver-focused feel while allowing comfortable highway cruising thanks to its overdrive gearing. The combination of the LS3 and T56 transforms this Cutlass into a car that can be driven daily with confidence and ease.
The chassis has also been extensively upgraded with a Global West suspension system, dramatically improving handling, ride quality, and road feel over the factory setup. The result is a car that maintains its classic muscle car appearance while driving with the refinement and confidence of something far newer.
Visually, the car retains the timeless styling that made the 1970 Cutlass Rallye 350 so iconic — long body lines, aggressive stance, and unmistakable Oldsmobile character. It keeps the old-school look enthusiasts love while hiding a thoroughly modern driving experience underneath.
The Rallye 350 models have become increasingly desirable over the years due to their unique styling and limited production, and examples restored to this level are becoming harder and harder to find.
