Help Me with a Pro Stock Camaro Motor

[ScaleDale]

My next Pro stock project will be a 2010 or so Camaro and I'm looking for info and references. I have all I need on the body, but for some reason there is less on-line about the engine in these cars than the elusive Ford hemi, even though the Camaros outnumber the Mustangs by, like, 10 to 1. Can anyone fill me in as to what power plant is under the hood of Jason Line, Mike Edwards or the Summit car? Please post either links to 1:1 references of engines or suggestions of kits to use for motor sources.

Thanks in advance.
