If it takes you two weeks to swap, you aren't a very hands-on person. It should take 4 days tops running into several problems. Oh, and don't argue with that, I put mine in my car myself and it would've taken 2 days if it weren't for some minor probs.
You do not have to replace your distributor...don't know where you got that from.
Get a new radiator??

Tell me year of car and what motor and I will tell you what hoses you need.
Are you sure you've done this before?
