help on swap

well i'm thinking about jumping into a project here. one of my neighbors is trying to sell me a '67 cuda convertible for $1000. the only snag is that it doesn't run and it is a 6 cylinder car. how ever a friend of mine has a dodge rv that has a 440 6 pack in it and only wants $800 for it.

so i want to find out how difficult this swap is going to be before i spend any money on it. i know that the front frame has to be modified, as well as a stronger transmission, driveshafts are going to have to be made, and that the rear end is going to have to be swapped.

i don't want to blindly go in and start hacking the frame so are their any kits for the engine bay and motor mounts that can make the motor go in easy and quickly?

also this car is automatic and i don't intend on swapping to a manual just for the fact that i think its a big hassel for nothing. so can i get some recommendations on a transmission? i know its gonna have to be a 727 but i don't think they were all built the same so i need vehicle lists on which car or truck i can pick one out of.

thanks in advance for any help
