Re: Header Collector Size Question
Trying to find a set of headers that would fit my application was a huge headache. The first set I had was the Sanderson Street Rod headers, but all they are is a set of glorified manifolds. They worked great, but on my quest for more power, I needed a set of full length headers. Mark McKeown and I talked it over and decided on a set of Hooker Super Comps for an 80-86 F-Series truck with 351m/400 in it. That also meant that the headers were designed for 2v heads. Mark adapted the 2v flanges to suit 4v flanges. So now I have a set of 4v headers that would work in my truck. They are made more for torque due to the 1 3/4" primaries into a 2 1/2" collector. But I'm thinking if I could make it a 3" collector, that would gain me some mid/upper range hp, plus the 3" exhaust with mandrel bends should really let it breathe.
