You can buy a complete 6.0 Ellis (well actually a iron block LQ4) for around $300 to $600 on Craigslist. Build it up with heads & cam for n/a 450 rwhp and put it in a car of your choice. Add nitrous for fun. Or just boost it with a cheap turbo or something. Here is a cool link about a iron 6.0 ellis making 1360hp on stock heads, crank, and stock block.
