For some of you starting your swap you may want to consider this . I just found it at ls1tech . Holley hads a complete swap hardware for the 73-87 . Due out at the end of the month it looks like .

This will take the guess work out of what you need .

What needs to be modified for the F body pacesetter headers to fit? I know I used these on my G body swap and it took some extensive moving of the tubes to make them work. I can't imagine there will be much more involved in the trucks as opposed to the tight quarters of a g body frame.

I know it's an old thread but Dougs headers D314 seem super nice and fit well. My frame is a 69 but since I have a 73-87 K member and motor mounts the fit is the same. 1 7/8 primaries, coated, and V band clamps at the 3" collectors
