building a engine trans set up

[kglowacky]

My last build I bought my LS1 and 460E together complete with pcm and harness (drop out). I have a chance to buy a ls1 Engine only (no harness or PCM) out of a 02 Camero at a good price. How complicated is it to get a trans and harness and pcm to make it as a Dropout that is as easy as the dropout to install in my new project or is it still better and safer to by a drop out complete. I assume the corvette LS1 motors would be the same. Are the PCMs different for every app. or are they standard with all LS1.
