Ted - the practical advice is sell the V6 car and put the money toward a V8 car, you'll be money ahead this way. An LT1 out of a '93 - '97 Camaro would be the easiest retrofit but you need everything from cooling system, engine, trans and computer to get started. My understanding is the engine cradle (like a sub-frame) is different from the 6cyl to the 8. It's not going to be like yanking the inline 6 out of a 1st gen, changing the mounts and dropping in a small block...
By the time you finish funding this swap you could have sold the '94 and bought a decent '98 Z28 with an LS1 and made the 1st installment on insurance...
