Buying My First Muscle Car 1973 Duster 340 Interior Pic

Ok, all that made sense to me. I also read that a 360 would be more worth my time as it's easier/cheaper to get parts for it. My thought process now is if it has little rust (and just the spots he told me which is a few spots on the trunk) I could buy a running 360 and have a mechanic drop it into the car for me.

You don't need no mechanic to drop it in for you. First thing you need to do is buy an engine stand from Harbor Freight for the 40 bucks. Then you can rent if you have to a motor hoist and drop it in. Just unhook what you have in there and repeat the process in Reverse putting the new motor in.
