just curious: watching the motor trend channel on tv. a lot of the restorations are installing "crate engines" 1000 HP +-. to what purpose is this for, vs. what came standard in the muscle car era ie. 327, 383, 426, 427 cubic in. just what can you do with 1000 hp. in a street car. i do understand that fuel injection makes a much better engine; but why the hp??
