GT40-P engine swap
Does anyone know of a header or exhaust manifold that will work on a 5.0 with GT40-P heads in a 67 mustang.
Anyone who has read many of my posts know I dont particularly like the head, but someone brought me an engine that had them to put into this Car. I have done the exact same swap in the past and had to build a set of headers, do not want to have to do that again. Any Ideas would be greatly appreciated.

Central Coast Mustangs makes them (gt40p specific)for 79-up Mustangs as well as F150 if it's possible to make them fit. If they do it shouldn't be too hard to have a shop build some pipes behind them. I'd call summit if I were you, they have all kinds of stuff thats not listed. You know about them using non standard spark plugs, right?
this page has lots of info that I haven't read all of, maybe it can help: http://www.stangpro.com/

Go to the page I described and "Find" the word "plug". Read the paragraph it takes you to. Basically you must use 98-up Explorer/lightning/cobra plugs in it (not shorty plugs).
Not too imp., when I first mentioned it I had read somehwere it was GT40p specific(not so), any gt40 plug will work. Just don't use standard 5.0 plugs.
Talked to my uncle (I was looking at his Explorer) and he says that there's a guy around here that did a similar (model year) build and found long tube headers that worked out of the box. Unfortunately, thats all the info he had. Hope it works out
