Thinking of making a purchase on a 67. V6 351E Questions...

[chewychevy67]

I am thinking about buying a 67 gmc 3/4 ton. It does run and drive. Has air, powet steering and brakes.Now I have never had a v6 351E before. They were not available in Canada and are super uncommon here. Are these hard to find parts for if I ever need them. Are they fairly solid engines. It has an auto transmission. I believe a 400. It is 50 yrs old so I am sure it will need some tlc just want make sure I am not buying something that I can't get parts for if needed in the future. Here are some pictures.
