I have a photocopy of a "HI-Rank corporation building the hydro for street and strip" manual from 1963. Shows info on valve body and other parts interchange between brands such as,Hudson, Olds, Nash,Kaiser etc..... Just send me your mailing address and I'll sent it to you.
I had several requests for this book. So I'm looking for someone that has access to a good scanner and is willing to e mail it out to those who want a copy. My scanner*****s. It was unreadable. So, If you want to be the "keeper of the knowledge" , and will agree to share it via e mail, I'll send it to you. It's about 150 pages. I'll let you know
