I like the GT-40. If you can make the trade do it. You will like the great low end that these intakes give you. They keep the shift points relativly low too, about 5800rpm is where most people with these intakes shift at. Add a blower...WOW, big block torque. I am very happy with mine, but the quest for nines will probably cause me to buy the performer rpm.
