[New C7]

At one time, only a few shops in the country had the knowledge and experience to create really fast cars. Names like Lingenfelter, Hennessy, and Callaway come to mind.

Today, there are many reputable shops around the country that compete head to head with them and I would not hesitate to send my car to them. Hennessey doesn't have this market to itself. The guys I know who had them do work on their cars won't go back.

A 1,000 hp LT1 will need a lot of money and time to do. I would guess the stock PCM will be replaced by an aftermarket one. As will 90% of everything else under the hood.

Cars modified to this power level can be troublesome. Putting 1,000 hp to the ground on the street is very difficult. Rolling on the throttle will end up with tires spinning or getting sideways. Not pleasant. 500-600 rwhp makes a nice and somewhat reliable street car.
