I wonder if Hooker made those drawings when they made those headers for my friend Moto's '66?
He put a 340 in it and called them about headers for it.
"Bring the car, leave it here. We're working on a pattern for that combination."
Left it there for a week and they called him to come pick it up.
"There go. Enjoy. Thanks for your help. No charge."
