Opinions on 360 vs 440

My friend has a 69 Dart with a 440. I helped him make the swap. He got rid of the power steering and power brakes, If I remember correctly he got the headers from Schumacher, this was over 10 years ago. Those headers where easier to install than my Hooker headers in my 360 Duster, I have power breaks and ps. I love his car, he works on it without much trouble. I curse how tight everything is at the drivers side in the engine bay with the headers and pb and ps and a 360.
