Hello All
Thinking of swapping headers, but want to know if I am wasting my time and more important my money. Motor 584 bbc 1000hp Here is what I run now, dynatech chrome 2 1/4 to 2 3/8 to a 4 1/2 collector, looking at some performance welding headers, 2 1/4 to 2 3/8 with a 4 1/2 merge collector 3 1/2 throat size. Here is some visual aid of what I have and the ones I am looking at. Have any of you swapped before or any other thoughts ? thanks
