BBC Hooker Headers
 

My build is a big block too. Any idea on the primary tube diameter? Or a part number as Tommy mentioned?

2" primary 3.5 collectors.
hooker not sure on the part # had a look at their web site but no luck.

You should be able to look at the flange where they bolt to the head and they will have a 4 digit part # and date code from when they were built.

I just had my headers built so do not need a set now but one more vote for BBC here. BBC / Tall Block even

I know this is an old post, but any clue if they'll fit a 70 chevelle?
