if you use a nissan engine for example you have to go thru the hassle of mating the old wiring harness with the nissan harness (assuming you are using a efi type engine) if you go the V8 route then you hafta deal with the extra weight issue, engine mounts, cooling ie larger radiator then routing a whole new exhaust and by that time the amount of money spent would be more than buying a stock replacement crate long block
just my 2 cents
