Here's the thing, the LF3 (I think that's the name for it) returns MPG on par or less than the LT1 V8. They produce similar HP numbers as well with the V8 having the slight edge. The V8 is much less complex, which means it costs less, and it is more reliable. With that in mind, I don't see this engine touching the Camaro. Chevy HAS to offer this car with a V8, but they don't have to offer it with a TT V6, since part of their customer base looks for a SB V8. Personally, I think this engine was created to allow similar V8 hp numbers, yet have a more refined engine for the luxury market. A pushrod small block chevy is certainly not refined for a luxury market, so they made the LF3.
