I'm not 100% sure, but this looks like an early picture of Paul Zielsdorf's Magnum Racing Engines Fiat long before he acquired it.
Here we have the Nanook fuel altered. Now resting in quiet repose in Bucky Austin’s collection. Sent from my iPhone using The H.A.M.B. mobile app
I followed it one evening decades ago and the trailer was substantial but it flexed and the slicks bounced... it was quite a show. My trailer at least had chrome wheels.
I keep the law happy with pieces of a blue plastic barrel for fenders. They pivot outwards for loading / unloading. CBF (crude - but functional!)
HOLY***** ! YOU HAVE MARKER LIGHTS!!!!! You must have a sponsor.. To be truthful, I wouldn't haul anything on my old trailer now.
