I have been chatting with a member here about 273 cams. He has a 67 273 already at +.060 with unknown pistons, cam, and heads. He already has the 4 barrel, ignition, good exhaust and rear gear to make it snappy. The engine is a fairly fresh rebuild so he doesn't want to get inside it except to change the cam for something bigger for more power. I am trying to talk him off the ceiling about it. That's a lot of work and expense to possibly go backwards. :BangHead::BangHead:
