Roush is NOT top notch but yes waaaay overpriced(I was stupid enough to buy into the brand name 3 years ago), call Keith craft and he will build you a motor that will kill a Roush for less money. Ford racing as well has crate motors that compare in numbers to Roush but cost 30% less. But go with the 427. You can never substitute for cubic inches.
