This 1975 Chevrolet Laguna S3 was built by Popular Hot Rodding magazine as a tribute to 1970s NASCAR. 175 miles have been added by the seller since purchasing the car on BaT in June 2016. At a build cost of $13k, the heavily modified 427ci small-block Chevy engine was dyno tested at 627hp and was built on a Dart Special High Performance block with Mahle flat top pistons, forged crank and rods, Dart ported aluminum heads, COMP solid roller cam, and Holley Ultra HP carburetor. The previous owner ran the Targa Baja California several times and had the transmission built and serviced, valves adjusted, and carb tuned less than 400 miles ago. It is being sold with a clean California title.

The two-stage Sherwin Williams Ultra 7000 paint was given a matte clear finish and shows some minor chips and track-related wear. Vinyl decals recall the look of 1970s NASCAR, but are removable if desired. Headlight block-off plates can be easily removed for nighttime operation with fully functional headlights.

The rear bumper was narrowed and sectioned and custom front chin and rear deck spoilers were installed. C-pillar opera windows are fitted with cover plates, and the rear windshield is equipped with blow-out straps. Year One 17×9 Alloy wheels are fit with older Continental 275/55R17 tires.

The half roll cage in the rear was installed by the previous owner. Scat ProCar 1000 seats wear Crow 5-point racing harnesses, and a custom console with a cup holder was fit.

Just Dashes of Van Nuys, CA refurbished the dashboard. The Grant GT steering wheel is equipped with PCS paddle shifters, and other upgrades include Summit gauges, a Powertrain Control Solutions GSM-5000 push-button controller for the transmission, and a Stewart Warner monster tach with adjustable shift light.

Dyno tested at 627 hp @ 6100 rpm with 561 lb-ft of torque at 5100 rpm, the 427ci small-block Chevy was assembled on a CNC machined and torque-plate honed Dart Special High performance short-block by mechanics at Dart Machinery in Troy, MI.
