A recent discussion regarding this issue.

I still have never come across a documented '67 425 hp which is a shame as it would make for a VERY neat car. I refuse to believe some dealers didn't install these as well and go racing.
P.S. can someone inform me how to post a link but shorten the address and make it look like "previous discussion" innstead of that long link. [img]/ubbthreads/images/icons/blush.gif[/img]
