I wonder what Carters those are? If your lucky they are the correct ones for the cobra lettered dual quad. The intake shown is not the same type that blue thunder repo's. There is more than one casting for these intakes that take Holley's. One of the casting included the firing order with cylinder 9. Some refer to them as the trans am intake. The blue thunder style is referred as the street intake. The runners are different between them. The Trans Am intake they say acts like a individual runner intake a wide open throttle. That intake could use much bigger carbs but thing might suffer for normal driving.
