Go to
http://www.camaros.net/forums/index.php and search 327, especially look for posts by pdq67. Paul knows thse old engines. I'll bet you can spend all afternoon just searching & reading over there. Also try
http://www.chevelles.com/forums/index.php too. And maybe
http://www.hotrodders.com/forum/ Those sites offer so much info that can be used across makes/models, it's nuts, especally Team Chevelle & Hotrodders.
