Back in the day we just called em hot rods...anything that wasn't stock was either a custom, low rider or a hot rod.
Hard to explain but you know one when you see one.
Other spin offs used:
Rat rod
Panty dropper
Lead sled, bondo barge
Street freak
Kustom
Retro rods
Shaggin wagons...that ones for Lenie
I'm sure I'm missing some
Economiser, I'd love to see that camaro and get the details. Heck I'd be happy with 450hp and 15mpg!
