LOL

Besides, if GM is going to spend money on a low volume engine (5.7L) for a low volume car (Camaro) it better be HUGELY profitable and it won't be. For the most part the manufacturing and material cost for a 5.7L would be the same as a 6.2L but you want it in a lower cost version of the Camaro? Nope. Maybe the truck version of the 5.3L because it exists but even that would still require a significant effort for development.

And here I thought I was the only one who thought like that.

To be fair, there is some low hanging fruit that tuners can use that GM calibraters can't take advantage of due to EPA requirements and/or long term durability concerns.
