[VIDEO] Dennis Collins Rescues a Motorless 1968 Corvette Originally Built with L89 Aluminum Heads

The hunt began before sunrise. By 5:30 a.m., Dennis Collins and his Coffee Walk crew were already rolling west toward Cedar Creek Lake, chasing the possibility of uncovering one of the rarest C3s Chevrolet ever built: a Holy Grail 1968 Corvette L71 with L89 aluminum heads, a combination produced in only about 600 cars. For Corvette people, that kind of lead makes a 90-mile drive feel like a quick errand.

The trail led to Mabank, Texas, where the seller met the team and guided them to a storage unit in nearby Tool. He’d owned the car for three decades, never realizing its significance until he pulled the gas tank and discovered a surviving fragment of the tank sticker — the only reliable way to confirm an L89 in 1968. That fragile scrap of paper changed everything.

When the storage door rolled up, a Safari Yellow ’68 emerged from the shadows, untouched since 1996. Dust coated the body. A custom hood — an L88 bulge grafted onto a 427 hood — gave the car a wild, period correct street machine look. Side pipes and Western wheels added even more attitude.

Inside, the odometer showed 66,000 miles, and the car retained its original M21 close ratio four speed, manual windows, and no A/C — exactly what you’d expect from a factory big block performance build.

But the real treasure was that tank sticker fragment.

Collins says confirming an L71/L89 without documentation is “not impossible — very difficult,” adding, “having the tank sticker is the whole key to this car.”

Fortunately, the right portion survived, revealing:

• L89 aluminum head 427
• L71 Tri Power option
• M21 transmission
• Tinted glass
• Headrests
• Standard black interior
• A genuine L71/L89. One of roughly 600. And it had been sitting untouched for 30 years.

“What’s funny is Chevrolet didn’t change the horsepower rating,” Collins notes. “They still called it a 435 horse car. Obviously with aluminum heads, I’d imagine it’s closer to 450 like an LS6. But they marketed the aluminum heads for handling, not power.”

The storage unit was packed with original components — seats, door panels, transistorized ignition parts, the original water pump, and boxes of hardware. Even the original gas tank was still with the car.

“He said the car had been here for 30 years … first time it’s seen the light of day since ’96,” Collins says.

The seller had no idea how rare the car was when he bought it. The team knew immediately.

After verifying the transmission stamp, VIN tags, and documentation, the buyer didn’t hesitate.

“How about I pay you what you’re asking?”

A handshake sealed the rescue of a true Corvette unicorn.

With no enclosed trailer, the team stuffed the Corvette full of parts, filled the engine bay with components, and joked about having Zach ride on the back holding the overflow. Panels came off. Boxes shifted. Dust flew. It was the kind of chaotic, joyful rescue only car people understand.

With the deal done, Collins began imagining the car’s future. He admits he likes the custom hood — a blend of stock and L88 — and the side exhaust and says the car needs “attitude,” maybe black stripes. “Maybe we black out the center of the hood like a ’67 Stinger,” he says. “Then carry some stripes over the deck lid.”

The crew celebrated at Shelly’s McClains Restaurant in Seven Points, a local favorite — and the same town where Dennis earned his first dealer’s license 41 years earlier. Steak and eggs never tasted so much like victory.

The day continued with a visit to a car purchased two years earlier from the late J.D. Pass — a stunning 1953 Corvette resto mod built on a 1987 Buick Grand National drivetrain. Then brightwork from a ’54 Corvette, electric door poppers, GN tilt column and shifter, custom chassis work — a masterpiece parked since 2012.

It’s now offered on Bring a Trailer with no reserve. Just one day remains and bidding is at $23,000.

Two extraordinary Corvettes in one day:

A 1968 L71/L89 rescued from 30 years of storage.

A 1953/Grand National hybrid rediscovered after a decade of sleep.
