The components will make a nice running street car. It should push a Camaro with decent gearing, converter, well tuned into the low-13's or better. I personally think it is a well planned one stop shopping for reasonable priced perfomance kit. It easy to do much worse.
In my opinion, Steve is right. Even big companies have some pride. They have tested their combinations during development and have concluded that the combination works or they wouldn't put it up for ridicule if it didn't. I wish all companies were like that.
