So….more header talk….this had me scratching my head

Mine is 418.
He said it might make more power with an 1 7/8 header, but with the weight of my car, it would be quicker to the 1/8 with a 1 3/4 tube.
Which these days has become 90% of my racing.
Certainly debatable, obviously. Just relaying what he said.


I get it. IMO, that’s why the dyno is so important. You can test both, and look at the curves because the curve is what’s important.
