oh, you built headers? BFD, so did i
and guess what? they added a nominal bump in power, only in the upper RPM with the combo that i was testing with.
you don't buy shorty headers when you're trying to make big dumb power. you buy them because of fitment issues, and because you either can't find, don't like the look of or don't want to spend the dosh for some 340 manifolds.
and before you start with some scientific process bullshit: it was the same engine, same car, on the same dyno. back to back, and yes, i did rejet and adjust the timing looking for more power.
welcome to FABO, we'd love to hear something about headers that we haven't all read, seen or experienced before.
