is it wrong to take a apart a perfect srt for its drivetrain?

so i am going to put a 6.1 in my 65 dart. i look daily for the right deal. problem is i never find them forsale in my state. you can find them on ebay. but then you pay shipping plus on average they want 5k for one. i got to thinking about something. so i am going to be putting my srt magnum up forsale to help fund my dart build. so here i am thinking i still owe 6000 on my magnum. i will have to come up with at lease 4000 for a hemi. (if i get that lucky) i could take the drivetrain and anything else i need. part the rest of the car out after and just pay off my car sooner. probably coming out paying even less the 3000 for everything i could need from a donor car. problem is am i crazy thinking about taking a perfect car apart to just junk it after? kinda sounds like a gas monkey garage episode lol.....
