They carry mostly late model parts, but they also carry a lot of stroker, ford performance, and race parts. They have the Canfields in stock for about $1000, stage 1 for about $1300, and stage 2 for about $1700. They also have the Brodix race heads for anywhere from $1400-3400. I think the Canfields would be a lot better suited for the street though.
They also carry the edelbrocks stock, stage 2, stage 3, and pro-race port and valvetrain. Almost forgot, they also carry the Holley sytemax kits and holley heads in stock, stage 2, and stage 3 versions.
They always have a good 3 or 4 page ad in muscle mustangs and fast fords. Hope this was of any help. I think they can help you put together a pretty wild motor.
