Big block A body spool mount K member?

I among a lot of other cars had stuck a 440 in a 73 dart sport I had which was a factory 340 car. It requires no modification to any mounts to make it fit right in the factory unmodified spool-type k-frame and chassis. All I used were 76 Chrysler Cordoba motor mounts for a big block. I also used a 73 small block k-frame in a 69 dart and did the same thing.
