Buying a wrecked truck from Copart?

So, I've been pondering putting a 5.7 hemi into my 68 Notchback. It's already got a 904, so all I need is motor mounts and some headers in order to get the motor to fit. Now, I'm on a tight budget here, and I don't really want to drop $1500 on a used 5.7 with 160,000 miles on it that I will have to get a bajillion little things for (wiring harness, misc. parts, etc.).

Sooo, my mester genius plen is to find a donor vehicle with a hemi that I can pillage. And fortunately, I live in Alaska; land of Subaru foresters and Dodge Rams. Basically, the local Copart car auction has a bunch of wrecked rams with Hemis that I could buy for (relatively) cheap, yank the engine out of and pillage parts from, and then sell to a scrapyard or part out.

Is that a generally good plan if I were to do this (biiiig if)? Has anybody had any experience with buying from Copart?
