Yes, these are Allison aircraft engines. The easiest way to distinguish them from the Merlin is that the valve covers taper at one end. I recall this 4-wheel drive beast from coverage in car magazines back in the early '60s. I found some more photos on Pinterest.com, a couple of which referred to it as "Quad Al," and another identifying the builder as Jim Lytle.

The Fiat Topolino body was a popular basis for drag cars competing in the Altered class back in the '50s/'early 60s. I don't know whether the rules for the Altered class actually allowed unlimited displacement or length, but I believe the car was mostly intended as a promotional attraction, performing demonstration runs and as a showpiece at various dragstrips and car shows.

I came across these ads for surplus Alison engines, which helps explain how building a car with four exotic engines could ever be economically possible. The first one was from the Feb '47 issue of Popular mechanics.
