I'd hardly call that a hill, despite its big name in motorsports. Still sounds like fun though.
http://www.climbtotheclouds.com/history/ Mount Washington Hillclimb claims to predate Shelsley Walsh by a year. I photographed there last year, some of it with a speed graphic. Plenty of cars with wire wheels. Didn't get the focal plane distortion I wanted; perhaps a little, but not much. I'll experiment more before returning. Spectators and photographers have to board a bus or van at 6am to be delivered to the various lookout spots along the track. You have to stay at your lookout spot (or within a few hundred feet of it) till noon when there is a break in racing runs.
So if I use 400 speed film, and shoot at tension 1 and 1/8" slit [1/350] @ f/16 and my 15" lens rather than the 7.5" lens, it should work!
You also need a car moving at a decent rate of speed. The old pictures of old cars were taken at races, and those old cars were faster than you might realise. The Locomobile "Old 16" was capable of over 100 MPH, and was built in 1906. Try it on a car going 80 and above. The wheels on the old cars were a lot bigger, too - don't expect the same degree of distortion on a modern car going at the same speed, even when the slit travel time is the same.
Doesn't a car like that just beg to be photographed with some focal plane distortion along with the smoking tires?
I saw that car in person in the late 90s, when they were running it with stub exhausts and preventing the rear springs winding up by chaining the rear axle to the frame. 12 cylinders of 122 cubic inches each makes a very interesting sound.

Well I do have 35" tires ... will those be large enough?

I leave the digital work for the urologists and proctologists.
