I was wondering the same thing about selling my engine and putting a LS1 in my car, but I have so much money in my engine it would be such a waste. I still havent found any units that really catch my eye. I agree I want to buy a complete setup. I get 3mpg right now and have lost my desire to even drive my car. I thought just leave it all alone any start on the next car =). I got a 32 ford 5window coupe body just sitting out in the yard begging for some attention. I dont know what to do, I havent touch my car in 2months and im very close to finishing it!
