most powerful production NA engine.

Re: most powerful production NA engine.
Ford's Single Overhead Cam (SOHC) 427 was based on the standard 427 FE side-oiler block, with a unique set of heads and a dummy cam stub in the usual position to drive a second timing chain 6-7 feet in length to spin the two overhead cams. Available over the counter from Ford for US$2,500, it made 616bhp @ 7500 with one or 658 bhp @ 7500 with two 780 vac-secs. A gilmer belt drive setup was offered by the aftermarket which solved the stretching problems associated with so much chain, something I just learnt from photos of Ron's SOHC for sale on ebay 08-Oct-2000. I'd love any other pics you guys may have to donate.
