Up for sale is a block out of a 1998 cobra that was parted out. It has just shy of 70,000 miles on it, standard bore, and has very minimal signs of wear. No visible cracks or damage. 

The teksid is the strongest production aluminum block for the ford 4.6 modular engine family. These blocks have been abused at levels well over the 1000 horsepower mark, making it highly desirable and they are becoming increasingly difficult to find standard bore blocks in good shape.
