I don't know much about the swap at all.
when I first looked years ago, prices were crazy for just the engines.
I found this site and it seemed reasonable for a turnkey job where the engine ran and transmission ran all together vs piecemealing parts and stuff from 5 different places in the hopes that it would run.
It doesn't seem that unreasonable if you look at it as a time/money thing finding all the stuff to make it run vs having one running.
but that is also why I asked. If I am throwing most of it out and spending another 5k on aftermarket parts to make it run, then it isn't really that good a deal.
