Reply to "me agene! (Question regarding Pantera headers)"

Just remember that an engine is baically a pump and all pumps need a little back pressure. I have a friend who had a good running Pantera with a 351c, cam, etc..He put the 180's from Precision ProFormance on the car (this was the only change at first and then re-jetting the carb and adjusting timing. The car ran worse than ever, and he had to put some restrictor cones in the exhaust(6 of them and some steel wool) to get the back pressure back, so he could get performance back to normal. Bigger is not always better. I think the 2 1/2" would be the correct choice.
