A few years ago I took it upon myself to rebuild my 75 Skylark. I bought a 72 350 engine to rebuild and put in it and completed the rebuild on the engine quite some time ago but it has sat in my garage since I finished buttoning it all up. I has been about 2 years since I finished the rebuild on the engine and due to negligence or lack of time or lack of helpers to get the damn thing in my Skylark it has been sitting there, which begs the question, is there anything that I should do to the engine before I put it in and fire her up? Also, my Skylark has been sitting for about 6 or 7 years, is there anything I should do to prep the car for the new engine? Clean the fuel tank? replace/clean fuel lines?
