“Wiper(d) many a Porsche and Cobras...”
Not mine, with blueprinted engine of 320hp. on a road course. Maybe at a dragstrip.
There was no Porsche that could have beat a model 400 and never a 200. I know because at the time I worked a a foreign car shop and we ran many a test. I don’t remember the 0 to 60 time, but was well under 10 sec. 289 Shelby Cobras were tad slower.
