From a book I have.
" Denny Larsen's Streetliner featured a modified fiberglass Sorrell body, tubular spaceframe, and a Ray Brown built, injected Chrysler; it turned better than 183mph on gasoline in 1954.
The car earned its nickname by being driven the ten miles back and forth between the salt and Wendover."
The pic shows that goes with that text shows the car without its nose, so the early injected Hemi, with a tall magneto sticking out over the block is visible.
