This has become a VERY popular swap as of recently (we sell mounts for this if you didn't know) so I wanted to post a few more pictures depicting what I have found to be the best method for installation.
Installation from the top via engine hoist works well but I recommend the use of a load leveler. I also want to note that I tend to make the rear chains a lot longer than the front so you can tip it a lot.
Also remove the extra sheet metal piece used on 323/m20 cars. It bolts right back up after the engine is in place but in fact allows for more room when dropping it in.
