May, 1955. Cover shot only, no article. Caption for the cover shot states:
"Often as not, the best horsepower is harnassed in the wee hours of the night preceeding the big event. While the engine pictured is not keyed to any of the coverage in this month's lineup, many will recognize it as a very capable unit. In the City of Burbank Streamliner, it became the first hot rod engine ever to break an official international record when the car posted a two-way average of 229 mph at the Bonneville Salt Flats. Owned by C.T. Automotive, Sherman Oaks, California, this one-of-a-kind OHV conversion unit is based on a '46 Mercury block. Hard at work are Don Clark and Jim Khougaz."
