I'm not an engine guy, so I don't understand all of the internals or intricacies of engine building. In many discussions about engines and HP, one question always comes up...What are you going to use the car for? For me, the answer is this: I will use it 99% of the time on the street for both short and long drives. Occasionally, I may want to take it on a track to open it up just for fun. I also want to be able to kick the $*#! out of the Vetts and the Vipers on the street.

Here's the hijacking back to the original post: The Ford Racing 460 puts out between 500 - 550 hp with 495 - 535 ftlbs of torque. The Roush 427R puts out similar numbers. They claim the Roush motors are complete up to the clutch. The Roush 427R is between $14K - 15K. The 460 Crate is around $6K. About how much would it cost to add the components necessary to get the 460 to the same stage of readiness for installation as the Roush? For what I'm looking to do with the car, is the Roush really worth twice as much? Do you generally get the difference back when you sell it?
