It is an ignorant remark to blaim Cloyes for the fact that the "ZERO" position on a 1972+ <a href="http://motorhaven.autoanything.com/">429 </a>and <a href="http://motorhaven.autoanything.com/">460 </a>engine was 4 degrees retarded. If you want to blame someone for you not researching this ahead of time, blame Ford, they were the ones who made this decision. I'm not flaming here, I just don't want a good company like Cloyes getting bad mouthed for other people's mistakes.
