I just got done reading a book called The Classic Chevy Truck Handbook by HP Books written by Jim Richardson. It mostly deals with the task force trucks. It has a great section on the 235. I have rebuilt my 56 235 and it brought back memories and I learned a few things that I should have done but did not do. Its a fairy small read but deals of stuff that will help the first time builder.
"As I lay rubber down the street, I pray for traction I can keep, but if I spin and begin to slide, please dear God protect my sweet ride." -Amen
