Schumacher headers 440 in 71 Duster

You don’t know **** about me. I was the 11th person in the country to purchase 2” CPPA headers in my 69 383-s. And when Roland Osborne told me he was unaware of anyone using them with a four speed as they were made for automatic trans only, I may have been the first in the country to make them work with a homemade z bar. So I know a little about this stuff. Everything done on a car is a compromise and it is up to each builder to determine how to best build a car that works for what they intend to do with it. Full length headers are not always best.
