Header choice
I'm doing this for a friend. He recently purchased a new engine online dyno'd at 375 hp. He already has MAC shorty headers from before. I told him long tubes would be better, but he is kind of on a budget. How much hp could be gained from going from MAC shorties to 1 3/4" long tubes, or maybe 1 5/8" long tubes. He says if its only like 10 hp, he'll save his money and keep the shorties. And he's gonna be buying 3 chamber flowmasters, I told him 2 chambers sound really cool on my vette, but he says they're too loud. Oh well, to each their own, hehe.
