I contacted an outfit in California that specializes in headers. After giving the stats on my new engine, he came back with an optimum configuration of 1 5/8" at the flange and step up to 1 3/4" to the side pipes. I'm already set up to have this done. I received an email from a guy who's running 2" tubes on his 408 stroker. The original dyno set up is running 1 1/2" tubes and he said the HP was reduced by 97 HP from 620 with the smaller tubes. I feel like I need to make a change.
