You don't need fenderwells for a 440...
Im using a set of Schumacher Tri Ys also TTI makes a header to
Many use these with a 440
A 440 swap is no more involved than a 383 or 400
I'm talking an early a-body. There's quite a bit less room then the later model a's. As far as I know, fender wells are the only way unless someone has another option with some pictures.
