The only header back exhaust I was able to locate on the Holley site for the 67-72 C10 was the Flow master American Thunder, do you have a part number for the Hooker set-up, the 300 SS series but if the 400 SS is all you have that will be fine. Update- I Googled the Hooker Blackheart 67-72 C10 and it took me to the page on the Holley site
