ive recently been considering doing an engine swap in my ute origionally i was going to buy/build and 350 small block chev, but now im wondering if im gunna go through all the trouble of engine replacement i might as well go for an LS1, this means ECU and wiring and all sorts like that but on the upside it could be cheaper, a mate just bought a written off VX SS for just over $2500, so my question is the a viable option? how much more work will it be? keeping in mind that this is a project car so time is not a major factor any advice/opinions welcome

ps i will have many more questions when im actually awake
