The 470 is definitely grabbing my attention. Mopar magazine even has a 2 part article on a 470 their building with trick flows.
It is now going to become a three part article. I have some intake and carb testing to do for part three.
Andy, why the 470 and not the 499 (4.125 stroke) or 512 (4.25" stroke)?
I know when you get into the 500+ engine size the stock cylinder port size starts to become a issue.
There are a bunch of reasons why I prefer the 470 in a B block to the larger engines. Piston height, rod length, windage tray fitment, torque peak RPM and hp peak RPM, etc. It just seems to me that the 3.91 stroke "fits" in a B block since all of the supporting parts such as rods and pistons etc. also "fit". When you run the numbers the 470 inches "fits" with a standard port cross section to put the torque peak at a "good" point. A normal car with normal gearing can use the torque peak and hp peak to run well. So like I said, a bunch of reasons like that.
