I have a org. c7fe hi-po cam, never used, for the 289 hi-po, its a solid lifer cam. It was going to be tested by gulf reseach in the 60's but never got in to a engine. For sale if interested ! $110.00 FRAN
I have one in my clone. It is a ford part . I have the installation sheet here in front of me if you need any 30 year old advice from ford. It sounds great. Idles OK. good grunt and it pulls to 7 grand in my 289. I chicken out after that . It sounds orgasmic with weber carburators on top of it. I had a friend who did that back in the seventys.
