Stock 49, that is going to be one hi-powered 216! If it's OK I'd like to learn a little more. How many cfm does each carb flow at 3.0hg? What is the total CID with the new crank and .030 over? Is the Hi- Torque crank an aftermarket part at the time? Thanks in advance for filling me in. CNC-Dude, this sounds like a great series of books to have and pass down to my Grandson. Am I correct that at least the first series of books are about the "Stovebolt" series of engines 1962 and older? Thats fine with me, I just hope that there will be a follow-on series covering the later engines. Let me know when Book 1 is avalible. Jay
