Repeat from the origional post.....
"I have a question regarding header sizes for certain power levels. I currently have a ~525hp 400 based 467 pump gas stroker engine with 72cc round port e-heads & OF roller cam, runs low 11's. can provide more specs if needed. its mostly a street car but sees some frequent drag strip time at test & tunes."
Forgot to add....
I know it is old material but keeping in mind others search out and could be interested in similar material for interest.
