Pair of Exhaust Manifolds for 1965-1967 289 Hi-Po Mustangs.These manifolds are constructed from original cast iron for longevity and are precisely cast for an easy installation. These are original on 1965-1967 Mustangs with the K-Code Hi-Po 289 engine, but will fit all 1965-1973 small block Mustangs. 289 Hi-Po clutch linkage may be required on non-Hi-Po Mustangs with a manual transmission.
Includes exhaust manifold studs and nuts for a proper installation to the h-pipe. Exhaust manifold to head bolts are sold separately. Sold as a pair.

will these work with GT- 40P heads?
I have read elsewhere that 67' hi-PO headers will clear the straight spark plug angle on the gt40p heads. Ford performance parts does make a nice set of stainless steel shorty headers that fit Gt40p's for a good price.

I put a 302 engine from Ford Racing in my 1965 Mustang, will the hi-po cast iron exhaust manifolds fit the 302. It has GT-40 aluminum heads?
No they will not.

Will these work on an early 302? Also, will I have to modify the existing exhaust to make these work or will they bolt in?
will work with any small block 289/302 with deck height of 8.2'' and you will need the h pipe for 65/66 hipo 289 for proper fit, they need to make an h pipe for these manifolds on a 351w deck height of 9.5

are these made in the USA?
We get them from different sources, so some might be, some might not be.

Will these work with gt40x heads and what size h pipe is used? Will it clear clutch cable conversion?
I just had a dusk exhaust put in with the originsl exhaust manifold. Will these be a direct replacement? No bending?

By Bill Tumas: We're here with cast iron exhaust manifolds for your '65-'73 Mustang. These cast iron exhaust manifolds are reproductions of the Hi-Po manifolds found on the '65-'67 K-code Mustangs. They will fit any '65-'73 with a small block. If you're running a non-Hi-Po motor with a 4-speed transmission, you will need the correct Hi-Po linkage to make everything fit properly. The kit comes with a pair of manifolds, and it comes with the studs that connect the manifold to your H pipe. They do not include the manifold bolts; you would have to purchase them separately. The flanges are all carefully machined to make installation as easy as possible. These cast iron Hi-Po exhaust manifolds are an excellent way to add a little horsepower to your early Mustang while still keeping that vintage look.
