Hey Guys, What needs to be done to make a GEN III Hemi work in a 71 Demon? Will it fit in the engine bay without cutting? Will the stock suspension support it, or does it need beefed up? What about maintenance of the engine afterwards, can you work on the thing? My son is thinking of doing this with his car and I'm not sure how easy of a swap this is. Would appreciate some practical real world advice from guys that have done it. Thanks!
