Original Cobras with 428s what hp?
Many original Cobras were sold with 428 FE engines. Were these the same 428 CJ engines that Ford put in everything else or did Shelby do anything to them to bring them up closer to the 427 FE?
Everything I have read listed the 427 SO at 425 hp, but manufactures were playing with the numbers a bunch back then. So much so that around 72 or 73 the Feds (think this is correct) stepped in with the ASE NET hp standard. So for that matter by todays standards what was the 428 and the 427 engines sold by Shelby actually putting out?
