I used to have a '78 Fiat with a dual overhead cam 4 banger with a tach which had a 6,000 RPM redline.
I drove it like a girl for the longest time, shifting at around 2,000 RPM. Then I saw the 6,000 RPM redline. So I went for it and revved it up to 5,000 between shifts, and holy crap that little motor made some sweet music.
The only problem was, when I was running on 100 proof ethanol (me, not the engine), at unmentionable high speeds with the top down, the turbulence would push the back of my head off of the head rest.
