Viper engine and transmission in my 1974 Dart Swinger

i knew a guy a few years ago putting a v-10 in a 69 charger there was a lot of cutting and fabricating involved to the inner fender , firewall and custom engine mounts. then he moved away so i dont know how it ended up. he had a lot of hours on makin it fit and a lot of measuring and test fitting. i have faith it can be done but it will probably take alot of work , but worth it i think.
