I am getting a set of free gt40-p headers ported. I have long tubes on my stock heads, and an o/r h pipe and a mac catback. What headers can i buy that are cheap and will hook right up to my o/r h for long tubes? Is this possible? my long tubes are currently bbk. if that made sense lol

gt40-p heads are the more economical heads to go with since they have a smaller valve, and flow just as good as gt40's.the better velocity and revised spark plug position make for a cleaner burn and improved fuel economy. They are also pretty cheap. It depends what you want? most people who go for gt-40 heads are for power only

well i know with a 1.7 roller rocker and a mac p headers, you should be well over 300. I'm not sure, but i think the intake on the 98 ford explorers (v8 of course) will fit. I'm not entirely sure. Maybe Darrel can shed some light on it.

well, you do have a AOD.. that could be robbing some power from you
