It’s a strategy that has worked consistently for gearheads throughout the ages – find the smallest car you can, and install the biggest engine you can. It’s a simple matter of exploiting power to weight ratio, and it doesn’t take a physicist or engineer to tell you that 350 horsepower will get 2,000 pounds moving a whole lot quicker than 4,000 pounds.
That’s probably the exact reason the guys from Roadster Werx decided to shoehorn an all-aluminum L33 5.3L truck engine into their 1969 Datsun 1600 Roadster – dubbed “Project Kaiju”. From our research we found that these dinky Datsuns weigh in at just over 2,000 pounds nicely optioned, and originally came equipped with a 1.6L 4-cylinder that wheezed out about 95 horsepower. By dropping in the L33 the guys at Roadster Werx are more than tripling the car’s original output – not a bad upgrade by anyone’s standards.
However, fitting a small block V8 into a car that’s less than 5 feet wide isn’t exactly a bolt-in-and-go affair. As you can see from the video above, the L33 takes up just about every available square inch of the 1600’s engine bay. It’s 11 pounds of engine in a 10 pound bag, but it’s still in the realm of possibility judging from their test fit. The car is currently being torn down for a full frame off resto before the L33 is mounted in for good.
