413 swap

I understand that if i had a 440 it would be best but I dont. There is no way i could find a running 440 with under 50k miles for 100 bucks. This is a budget build so im just gonna make the best out of it and see what happens. All i was looking for was advice on what the best way to do things with what i got and what problems im gonna run into with mounts and etc. Instead i got everyone telling me to get a different motor. Not alot of help guys. I just want to get it running.
