It's not a conspiracy Gary, it's just the Aero is better on the Pontiac body. Rules say the body can only be a 5 year old design so the Pontiac body will die a natural death... Of course being a Pontiac fan from way back (I still drive a Bonneville), I betcha the guys at GM gotta wonder sometimes if they didn't cancel the wrong nameplate!!!!!

As for leased engines, it's become very common throughout many forms of Motorsports....Much cheaper then having to have your own full time engine shop with all the personnel and equipment that's necessary to be competitive!
