Which opens up another conversation. Every interview I have seen with Shelby about engine HP ratings, he always says stuff like "Ford published 335HP to make the Feds happy, but that 428 Cobra Jet was putting out more like 500HP." Interesting that I rebuilt their acclaimed 425HP side oiler back to nominal specs plus a bit more cam and barely exceeded the "published" HP. Where's my 100+HP bump that was supposedly "built-in?"
