340 for Cruising and Fun 1/4 mile Passes

I had a Crane Fireball in my 66 390 Fairlane with 3.89:1 when I was in High School. That S.O.B. would stripe the neighborhood at will... and it earned me a restricted driving license to boot...
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.
