Looking for information on Clifford performance headers. I bought one of the long tube headers that is supposed to fit a 250. I have a 250 with C4 that started life in a 79 Granada. Notes say that you may need a mini starter for clearance. Problem I am having is that the front collector pipe actually overlaps the flywheel / bellhousing by an inch or so. Would require major cutting and welding to make it work.
