only thing i ever liked about ford racing aftermarket was there gears, other than that most of the other stuff is highly over priced and isn't really that good. if you look at there heads and what they charge there not worth it, other heads flow way better for less money, same thing with the intakes (gt-40, cobra, explorer), same thing with there cams, was good when they first came out just because they weren't other ones out for the industry, but now there still the same price despite other cam makes out there that make a better cam that chrage way less.
I'd either do the edelbrock or like i said a summit polished one.
