    350 SBC Cost?

    How much should I pay for a 1993 350 SBC out of a cadillac at about 150k miles that rotates freely. It originally was TBI, but was converted to carb. It comes with an Edlebrock carb and intake. I am looking to purchase it and upgrade the cam and headers. This would replace the 305 in my 1990 C1500.
