Crain Cams were a block from my home in Hallandale, Florida, before they moved to Daytona. Several of my friends worked there and I was given Fireball cams for my 340's to play with. I tossed them when I moved five years ago. I run the DC Purple cams now, but wish I kept the Fireballs, for a rainy day. I didn't think the parts of today were so crappy made. These cams were from the 70's.
