Anyone remember these? Used to have them on all the old pre-everything modern cars (rednecks did anyway). Can one be put on a 1990 model 5.8l without screwing anything up? They work off vacuum.
Wolf Whistles = An aftermarket option from the 1950's. Another option was the "Bermuda Bell." Old car mags from the 1950's had ads for these devices in the back pages.
Just wanted to slip this up front again. Any idea if one of these would cause any damage? I know that as soon as I use it the vacuum "leak" will drop power, just don't want to cause permanent damage. I'm past the point at whistling at girls, just can't whistle worth a damn and need to catch the attention of the horses or dogs sometimes.
