Although the sheetmetal reconstruction looked great, due to the Opel GT's unique chassis design, it created a whole new set of issues. "These Opels used monocoque construction, which means that the body panels serve as structural support for the chassis. They don't have a full frame, and they don't have subframes like a unibody car, either," Ricky explains. "The stock suspension attaches directly to the body, and since I cut out the floorboard I thought 'man, I better build a full frame for it.' I bought a Fatman Fabrications Mustang II front clip and a Quarter Max rear clip, then connected them together by making some custom square-tube framerails. My son, Callahan, and I did all the chassis work in our garage. Afterward, I channeled the frame into the body by building custom floorpans."
Space is at a premium in the two-seat interior, but it’s not oppressively small. To make r
Ultimately, Ricky amped up the Opel's visual kick so much that pictures can't accurately convey how seductively voluptuous the car's proportions are in person. To put things into perspective, stock Opel GTs measure nearly 2 feet shorter and 8 inches narrower than a 1968 Corvette. A car this small packing 315mm-wide rear meats, massively flared fenders, and a sinister stance looks borderline ridiculous, but in a very good way. Given the Opel's diminutive dimensions, Ricky didn't want to ruin the car's balance with a big lump under the hood. "A small-block Chevy would have made the nose too heavy, while an aluminum Buick 215 only weighs 280 pounds. Since Opels were originally sold through Buick dealerships, I thought it would be cool to put a Buick V-8 in my car," Ricky says. "After GM sold the tooling and manufacturing rights for the Buick 215 to the British Rover company in 1967, they became very popular in the U.K. I figured that if people figured out a way to shoehorn a Buick motor into small cars like MGs, Triumphs, and Morgans, then it should fit in an Opel GT, too."
In order to get some more grunt out of the all-aluminum mill, Ricky shipped it off to McMurtry's Engines for a complete rebuild. The Buick was bored .030 over, fitted with a fresh set of pistons, then finished off with ported factory cylinder heads, an Edelbrock 500-cfm carb, and a Crower 214/218-at-.050 hydraulic flat-tappet. Although Ricky has never strapped the engine combo to a dyno, he estimates output at roughly 300 hp, which is more than enough for the 2,800-pound Opel. The motor is tied to a Tremec T5 five-speed manual transmission, which channels torque back to a Ford 9-inch rearend.
Considering this is a hobby built on backyard engineering, the tale of Ricky's Opel GT will resonate with people who have never even seen one in person before. The fact that a devastating wall of saltwater served as the impetus for such a wild creation makes this saga that much more impressive. It kind of makes you scratch your head and wonder, what have you got to lose?
