It will all come down to what it is you are looking for. Easy install, high horsepower, high rev, light, cheap, carbed, FI, new, old, etc etc. Get the bible( V8 conversion manual written by Mike Knell from JTR) he documents what I would call the easiest swap with a non nissan engine that I have heard about. But I feel from reading stuff here that it is all a matter of opinion. I don't think two people here have the same engine exactly in there car that isn't stock.
