KRC performance Is the only place I know of that has supplies of 4.7L performance parts.
http://www.krcperformance.com/ I have been told that the 4.7L uses the same bell housing bolt pattern, motor mounts and flex plate bolt pattern as a 5.7L hemi. I don't know if it's true or not. I had a crazy idea a few years back to install an aftermarket ford flathead distributor to the valve cover and drive it off of a camshaft. I would run a megasquirt ECM and it's running.
