Beside a dryer in a woman's basement sat a 1960 1600S motor, one lift away from the trash. The woman clearing her parents' estate said she would have discarded it herself if she could have carried it. Instead, Vu Nguyen answered a Craigslist listing, called a friend with a truck, and hauled it away. That free engine began a Porsche 356A build that took roughly 10 or 12 years to complete.
The original plan was simple: rebuild the engine, find a donor vehicle, and have a usable 356 ready by Nguyen's 50th birthday. Then the supposed donor turned out to have its original engine, transmission, and body panels. What looked like a simple engine swap became a familiar question for anyone working on old cars: preserve the matching numbers, or use the car as intended?

The free 1600S motor that started the build
A Craigslist advertisement offering a free Porsche engine demands a quick response, along with a truck and realistic expectations. It could be a bare block, have seized internals or missing pieces, or have spent decades collecting moisture. Nguyen and his friend instead found a complete enough 1960 1600S motor from a Porsche 356, sitting beside the dryer as the property was being cleared.
The painful part was what had already disappeared. A 356 body had once been on the property, but it was gone before Nguyen arrived. Other Porsche parts had been thrown away only a few weeks earlier. He concluded that the woman's father had been gathering a body, engine, and parts to assemble a car but never finished it. Once the rubbish had been collected, those pieces were beyond recovery. Timing saved the motor and nothing else.
Nguyen kept it for roughly 10 or 12 years. He was not chasing a concours car or an expensive restoration. He wanted a sound 356 that ran properly and could be parked without constant worry. He described the predicament accurately: champagne taste and a beer budget. A free motor helps, but it does not make the correct body cheap or easy to find. Most decent 356s already have engines, while engineless cars usually need far more than an engine.

How the Porsche 356A build stayed hidden for a year
At about age 48, Nguyen handed the motor to Steve Hoffman to strip and assess. Hoffman helped rebuild the 1600S into a 1720cc motor. Nguyen estimated that the original specification produced roughly 70, 75 horsepower; the rebuilt combination should make 85 to 90. Those figures are modest, but in a 356, the engine's condition and assembly matter more than a dramatic number.
The search then moved through personal connections rather than advertisements. Nguyen remembered a black 356 at his friend Pete's place in New Jersey and called about what he thought was a 356B. Pete corrected him: it was his wife's 356A, which they had owned since the early '80s. Nguyen and his wife wrote a sizable check, though he considers the car effectively a gift. The price was far below its value, and Pete understood what Nguyen intended to do with it.
The 356A had been sitting for at least 10 years. Rather than bringing it home, Nguyen stored it with Bob Miller at Speed, where they could handle the basics and prepare it properly. His wife knew he had bought the car, while his children knew only that he had acquired something. He kept the details quiet for a full year, no easy task for someone surrounded by Porsche people, until the car was unveiled for his 50th birthday.

Why matching numbers did not end the build
The surprise was that this was no ordinary donor vehicle. The engine needed tuning and the brakes required attention, but the car started and ran well after sitting for at least 10 years. A check of the numbers established that the 356A retained its matching engine, transmission, and body panels. Only the color was not original. Nguyen had not insisted on matching numbers when he bought it, so the discovery changed the job without changing his reason for owning the car.
His answer was "matching numbers plus one." He kept the original engine and installed the rebuilt 1720cc motor. That allows him to flog the car without putting the matching block at unnecessary risk. The arrangement is sensible: preserve the component that cannot truly be replaced, then run the prepared spare. No stamp on another block can make it the original engine, however well the replacement performs.

Matching numbers can change an older car's value by a few thousand dollars to six figures, but that matters most during a sale. A non-matching car can still have the right appearance, road manners, and mechanical condition without commanding the same premium. Nguyen does not plan to sell this 356A, so usability wins. He also respects the spare motor's history. If he identifies its original chassis, he says its owner could have the engine. Until then, the 1720cc motor protects the matching engine while keeping the 356A on the road.
