----I think none of us has wanted to venture a value opinion because we dont know what condition your LS6 find is in. Is it overbored? Is is the crank standard or cut? The list of variables go on. A virgin LS6 has one value. A raced and abused LS6 has quite another value.......Bill S

----And,,,Throw into the equation that there were many more crate LS6s than LS7s.
