My 350 into my '77 280Z was my first swap (I'm 50ish, but working on cars all my life). I agree with everything above, except I did not need a welder. For the couple things I needed welded, I had a friend with a welder do them for me. I could not justify the cost of the welder. The lift, JTR book, basic tools, a plan, budget and a realistic time table are all very important.
