I suppose because he may not have a spare $10K hanging around and as I have been privy to the cost of some parts it will be quite funny to run 9's on an engine that will owe him/her what this will. Like Jessica says its more than just an engine its a complete build so the budget needs to be spread out, we built an engine that did 1000hp on the dyno and just for 1 meeting while the 3.4 was being mended, to a shop its no biggy, I threw the motor for the silver car together on my workshop floor the night before it ran the first 10 and the bottom end stayed in the car for over a year.
