I'm not being arrogant, have you had or done an early A. It takes more than a motor. Just because I prefer one motor over another does not matter, it is my opinion. We all started where he is now. If one wanted to swap a V8 for a /6, the best advice I could give, is to get a donor car. Early A V8 cars and all that goes with it are hard to find in todays world. 318's have never been hard to find. They run forever and usually outlast the body. An Early A has more than a few peculiarities and some things special to them. It's not about you.
