I’m adding some specs pages on the Ford engines offered in the Shelby Cars from the 260 cid to the 428 Cobra Jet. Each spec page will show the different variations of that particular engine. For example the 289 came in a 2 barrel, a 4 barrel and a high performance version. Shelby used only the HiPo version in the Shelby cars including the Cobras, the 1965-66-67 Shelby Mustangs. I include the latest version of the Ford small block, the Coyote, just for comparison.
