The United States doesn't have a gun control problem.
We have a people control problem.

In the early 60s we used to drag my buddy's '58 Chevy. We of course finger painted all kinds of slogans on it, but those we did put on were painted using Bon Ami souring powder ("hasn't scratched yet") and water. Used the same stuff for windshield prices on used cars at the shop where I worked.

still remember when the wanabe street guys with more money then brains had a hole in there hood (usually not done real well) and a tunnel ram on it. Add a couple double pump holleys and a cam and you had an engine that was about useless under 3500 rpm. Looked cool though. Spin a stock bottom end motor fast enough to take advantage of it and rods tended to seek daylight and valve spring life was measured in hours!

From Engine Labs

Occasionally the term “ĺ race cam” pops up in conversation, usually with veteran hot rodders or nostalgia groups. Sometimes you’ll see it in print ads and online product listings. From a purely technical viewpoint it means little in the way of explaining a camshaft’s performance potential. It’s just one of those glorious reminders of the early days when camshaft grinders had furious rivalries on the track and in the media. It’s also a significant milestone in a developing enterprise that snowballed into what we now recognize as the street-performance market.

The original 3/4 race cams are the forerunners of today’s street-performance grinds.

The term likely originated in the ‘50s as the burgeoning hot-rod industry was modifying Ford Flatheads to drag race on airport runways and attempt top-speed runs on dry lake beds. The legendary Ed Winfield was one the early pioneers in grinding camshafts with more aggressive lobe profiles, and the cams were often labeled as full race for promotional purposes.

“And then some guys wanted a milder cam that could also be used on the street, so they called it a three-quarter race cam because it didn’t have as much duration and lift,” explains John MacKichan of the Speedway Motors Museum of American Speed in Lincoln, Nebraska.

My neighbor growing up had a '69 Camaro with a "3/4 race cam" in it. I was always curious as to exactly what that was all about. It makes perfect sense now, he spoke of it like it was a real name for the grind while I always just figured it was a catch all for a streetable grind. Seems we were both correct. That son of a gun would get right with the program too.

Anyone remember the foot actuated windshield washer pumps? My buddy's were convinced my wipers knew when it rained. I'd just bump that foot pedal for a wipe like delay wipers now.

I had a 47 Linc. coupe that had a foot switch to change stations on the radio not many cars had those. Then there was the wonder bar radios where you just massed a bar on the face of radio to change stations then there was the vacuum wiper motors when you started up a hill they stopped working unless you let off the gas.

I am amazed, truly, that they have been gone for over forty years.
At night I still hesitate to put my foot in a certain spot for fear of putting them on bright in town.
