My New Toy 1968 Barracuda Fastback Formula S

Ok so I went to the secretary of state today to transfer the title and now the car legally belongs to me, so now I can start working on it. One of the things that I want to make sure that I understand is the 340 that is going in this car is a 1971 so after reading a few articles on here it looks like I will need to change the timing cover and water pump in order to make it easy to set the timing and hook up all the hoses and 68 brackets correctly. I believe the oil pan is OK to use, and oh yes I need to change the balancer also.
