I am considering doing a 350 swap. The current 2F in my 78 is looking less and less promising and will definitely need to be rebuilt, and I don't want to continue to throw more money at it. There is a good deal on a 350 close to me, is it worth it to do the swap? How hard would it be and what would the costs be outside of just the engine? Would it be more wise to just rebuild my current engine. I know that the previous owner already rebuilt it and it continues to look like he did a poor job, and I am worried about bigger underlying conditions that I have yet to discover.
