Paul,
I too offer my condolences on your loss. You had many more years than some do but there is never enough time with Dad.
Me and your dad did have some conversations about engines and how he was sitting in chair directing the work on the cars just a few months ago. He, in my opinion, was the most knowledgeable person on Ford engines of any type from the flathead to especially the 351 C and Boss 429. He was always modest about his knowledge. I had hoped to pull some of it in my next engine build.
Welcome to you into the Forum your dads post will live on here for sure.
