those were all over 20 years ago, a friend had a 70 road runner, he cut the hood so that scoop was just over the hood, and had the linkage hooked up. no guessing if he was full throttle or not with that set up.
and there was a late 60's chevelle that was air bushed on the sides, QUAD ZILLA. it had no hood, ever that i saw, bb chevy, with a huge ass blower, tunnel ram, and dual quads up top, and that scoop. all chromed out. it was tubed, full cage, but all show car, i dont know if he ever ran it, wasn't a friend. i just saw it all the time as a kid. left a burnt image in my brain, it was a sick set up.
