Change headers on my 69' Country Squire

[Toppa]

hey folks,

I was one step away from buying an old header of a mustang 67' for my 390. fortunately I a look under my hood yesterday and recognized theres a beam freakin tight to my stock headers

So my question is:

anybody knows which headers will fit into my car?

wanna improve my flow because I read about worse powerloss cause of my mean stock headers...
second question is how much HP improvement I could expect from the swap?

lateron i could post a picture...

heres the part i wanna install : https://www.ebay-kleinanzeigen.de/s-anzeige/ford-mustang-1967-auspuffkruemmer-fuer-390-bigblock/532334745-223-17192

Watch this video and listen to the discussion after the last test to figure if this is worth the effort for your particular engine.

The price for the manifolds in your Deutschland auction is a pretty good deal, but they are not going to work in your car. Maybe.

oha. Nice... I will check later, cause Im in the bureau now

Those are 390 GT exhaust manifolds.  I don't know if they will fit, but they will not make any significant difference in power on your engine.  I tested a bunch of exhaust manifolds for my book, and the 390 GT manifolds were not much better than the stock log-type manifolds.

If you can find a set of 428 Cobra Jet exhaust manifolds, those would be a good step up in performance (assuming that they would fit).

for your book??

what will increase power in a header?

-diameter
-less turbolences

what else?

[Heo]

Yes Jay have Wrote a book where he compares different intakes and
headers
On the headers..... you got a 69 right? trye to find 65 factory shorty
castiron headers think they will fit your 69. Leakfree and dont rust out
like steeltube headers

[jayb]

Individual tubes like steel tube headers will help the most.  Here is a link to my book:

[Heo]

I'm talking about the ford castiron Hiperf Headers
not the log type manifolds just to clarify  Not that
big difference in power compared to steeltube
headers in a mild street engine

And i can recommend Jays Book interesting reading

[Toppa]

uhhh im really interested in the book, but honestly, over 30 bucks for shipping 
but you really got my respect for the book. seems to be really professional!

so maybe some steeltube headers are available at the german aftermarket.... dont believe that hi perf. headers are available...

FElony-
feeling like a noob cause ive recognized these long tube headers but never knew what theyre for....    but good to know that headers swap wont change that much. gonna watch more of these engine masters videos know. great link, thanks

Yes, unfortunately shipping overseas from the US is very expensive.  It is even quite expensive going to Canada; why, I don't know...

[cammerfe]

Because they can.
