Crate Motors

Why is everyone turning to crate motors? They dont produce big power as usually advertised. I spoke with a guy from a local machine shop(The Chevy Shop)yesterday and he was telling me alot of people are turning to crate motors.and its hurting machine shops that specialize in high performance equiptment. with crate motors all they have to do is install them. But if you really think about it, all their doing is punching it out .030 over and installing a $470.00 kit, and selling them as shortblocks for $3000 you are'nt very smart if you do this!
I could sell them all day long for $2250 and make a killing, but i would be a shark like the rest of the people that are killing the sport/hobby we love so much just to make a profit! dont make a mistake like this besides where is the fun in a crate motor?
