I am wondering if there are any headers even made for V8 F-150? I read another thread that said there are minimal power gains putting on shorties? I dont know what shorties are but I have to say I have never really heard of installing headers and getting only a minimal gain. I put headers on my little V-6 Hyundai Tiburon motor and got over 14 hp on a dyno. I assumed a big V-8 would get some very nice gains.
Let me know if anyone has any links or who knows of a company that makes them. Thanks.
