I'm new to the forum, but this is an old story that I've wanted to tell the group for some time now.
In 1987, Steve Karlock of Thousand Oaks, CA brought me a Kaiser Darrin for restoration, that had been outfitted with a Cadillac engine. As you can see in the first photo, the engine mounts were rather tall and cradled the engine higher than normal, since the steering box, which normally sat beside the 6 cyl, now rested underneath the left hand cylinder bank and prevented it from going further. The engine sat so tall, that someone cut a hole in the hood for carb clearance and mounted a J.C. Whitney hood scoop to cover the intake.
Steve told me at the time, that the car had been previously raced in the mid-fifties by Laura Maxine Elmer, who later married Briggs Cunningham. Evidence that it had been raced was found in a worn layer of brushed-on red enamel over the entire floor area, to take the place of the red carpet that had been removed, to comply with SCCA rules. The car was also equipped with a pair of side-exhausts, with no mufflers, that came off the headers. Actually, there was just one header on the left, fabricated around the steering shaft and the right side used a stock iron manifold, which bolted up to the r/h exhaust pipe. The modifications to the car were all very rough, looking they had been done in haste, so as we restored the car, we re-engineered some of the details, to make it more presentable as a restored item.
The car was equipped with a Lasalle 3-speed manual with an aluminum adapter to the V8. It had a giant 4-row copper radiator fitted into the front compartment, but the mounts were collapsing with age and fatigue, so we replaced them with stronger units. This wasn't going to be a very useful car if it was put back as Darrin's Sunset Blvd. team had built it, so I was given the go-ahead to install the engine correctly. This meant lowering the steering box bracket and fabricating new mounts that held the engine at the correct angle for the carb floats to work correctly. We made up a K-frame to replace the modified and twisted original crossmember. The steering shaft was also modified with a couple of u-joints to allow proper clearance and new headers were fabricated for each side, with a larger main, center tube, and two smaller tubes feeding onto it on either side, very period correct, if not as 'originally' modified. The side exhausts were rebuilt with short mufflers, to help improve street drivability. Steve had a complete dual-quad manifold from a '55 Eldorado, so we added that item, also. As you can see in the photo, it completes the installation very well. The electrical system was divided, in order to start and run the engine on 12 volts, with a voltage stepdown coil to run the original lights and instruments on 6 volts. A couple of weeks after that photo was taken, I drove the car up onto Steve's trailer and he took it off to another shop for upholstery. It ran very smoothly, just idling up the ramps.
It had been one of the group of cars shipped out to Darrin's shop. Kaiser was closing, so in order to make good on their styling and development deal with Darrin, they paid him in cars to settle the debt. The car was a regular production item, fully finished and bore a regular production plate, with a serial number, as seen in the photo. The story we heard from Darrin's family back then, was that Butch, his younger brother, handled the shop operations and it was his decision, when it came to some of the original modifications, given the short amount of time available for the V8 installations. Since we had the time, we were determined to do it a bit more patiently. the hole in the hood was closed and these days, the car looks exactly like any other Darrin, except for the side exhausts.
I haven't seen Steve or the car for the last 28 years, since I moved to the Midwest. But I have spoken to him recently about the museum he's opening in Hannibal, MO. The car will be on display there as part of a permanent exhibit and I'll take some better photos when I visit this summer. I have some other photos from this period, but they were all on old photo media and scanned for this thread.
