The Plymouth Weslake DOHC Motor from the 60's

I don’t have the book in front of me right now, but it was a book about building chrysler engines and IIRC it was written by Larry Shepard. If you google larry Shepard you should find the title of the book.
When time permits can u send me a picture of front cover of said book !!!!
I looked and the ones I seen look to modern etc
Thank you Chris
