I would expect this 1LE option on a SS to be comparable to a Boss. And a Z/28 comparable to the Boss LS. Both costing 2k to 4k more than said competition. Thinking about this I know it will not happen due to the fact GM wants to sell units and with a "real Z/28" being a niche car I doubt them ever producing one on par with the Boss LS, which would necessitate a LS7. Which by the way would not be rated at the vettes 505hp but then again I would not mind a 480hp LS7 in a Z/28
