360 magnum vs 5.7 hemi

I'm currently in the middle of an early 70's Challenger project and am putting in a 5.7 Hemi with XV Motors Carb kit. The engine looks brand new has less than 100 miles on it and I should be getting 430 - 440HP all for just under $3400 CDN ($2750 US). I am a HUGE fan of the old iron and still not sure if I am making the right decision......but....bang for buck......this is a good solution for me at the moment.

My problem is the price of ebody parts is killing me. I'm thinking of changing projects and getting a more completed 71 Dart. I posted a picture of it on this board for opinions. Anyone here have a 5.7 in their A Body?
