Hey, it said "Recorded 1970", so I call 'em like I see 'em.
I have about 40 of these tests, and I plan on putting them out on YouTube soon. I have the W-30 test that Canuck referenced, as well as a whole slew of other Ford, Oldsmobile, Buick, Mopar, and Chevy tests. No Pontiacs for some reason.
Next up, I'll load the 69 Charger 500 Hemi test, 70 AMX, 69 GTX, 68 Shelby GT500KR, and a few other cool ones. Some of my favorites are the full-sized Buicks and Oldsmobiles. They go through the cones like a drunken elephant on roller skates.
