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

i am up in air right now. i am finding it hard to tear apart a perfect car. tincup makes a solid point. sounds like the engine is all i may be after. i would love to use the nag trans but i may be making my life tougher by doing just that. i will test the waters. i have a local guy looking to sell one of his magnums to pick mine up. i will keep searching for a used engine. i guess i will stay on point take any money from the magnum sale and get my front end. thanks for the all the advise.
