I'm putting together some information cards and a Showboard to help explain what a K code is. I will display and distribute with my car at car shows. I wanted to make sure I had my facts straight. I got all this information from Tony's book, but mistakes happen. Please take a look and provide feedback. I can also make these available to anybody here if they want them.

Excellent Showboard. However, I suggest a couple of changes:
A bit difficult to see the .75% so I suggest 0.75% instead
or just say less than 1%.
Add the word at after rated, i.e. engine rated at 271HP....
High Performance fuel pumps had the same capacity as the
Standard 289. Only difference was the extra spring under the arm.

Would also add that the Special Handling package was included with all K codes, no matter if it was a GT or not.

No mention of the special crank prep.
Thank you guys for the extra set of eyes. I plan on doing some editing based on your feedback. Again, I plan to have this printed on the 4x6 collector cards to distribute at car shows. On the other side would be my car photos/design.
At a show or cruise, I may get 1 out of 100 people who look longer than 10 seconds at the car to recognize and know what a K code is. This is my attempt to educate the masses.

Hmmm - I attempted to make clear that the package was standard. My GT statment in parenthesis was to draw mention that GT cars also had the package. Maybe I could change it to, "(also equipped on A-code GTs)" Anybody else get confused when they read that?

What about the thicker 13/16ths sway bar, adding "balanced" to the fan description, and someting about the pinion snubber on the rear-end description?
I also believe that the Hipo exhaust mufflers were different than standard dual exhaust, but more knowledgeable folk here should be able to clarify that point.

The thicker sway bar is in there next to the steering box. I wasn't aware of a difference with the mufflers.
What exactly are 10.5:1 compression cylinder heads??
The engine has a 10.5 compression ratio. The cylinder head would be rated for combustion chamber size which was no different than other 289 heads.
"Cast in numbers" is just ambiguous. Don’t all heads have casting numbers??
“Oversized main bearing caps and connecting rods”, Larger or beefier or thicker may be more appropriate. Oversized sounds as though regular 289s were “sized”.
Just suggestions. Do with them as you will.
• 10:1 compression ratio [10.5:1 is wrong. Applies only to the 1963-64 Fairlane with the small-chamber heads, which Mustangs did not get]
• Special cylinder heads with cast recessed springs seats and screw-in rocker arm studs [cast in numbers is meaningless]
• High performance valve train including high-lift mechanical camshaft, dual valve springs, and hardened valve spring retainers. [mechanical cam and solid lifters is redundant]
• Heavy-duty main bearing caps [oversized not the same as heavy-duty]
• Heavy-duty connecting rods and special connecting rod bearings [rods were heavy-duty with special caps and larger bolts/nuts]
• Special high-strength cast aluminum pistons [not mentioned]
• Streamline cast iron headers [they were not very competitive]
• 600 CFM Autolite 4100 4-barrel carburetor [everyone knows the 600 cfm is the big 1.12" venturi]
• Low profile, open-style, high-efficiency air cleaner
• High performance spark plugs [not all HiPos go the solid core wires. Ford moved the solid core wires to the RPO option list starting in 1965.]
• Large 4" alternator pulley [aluminum case 42 amp alternators were on all Mustangs in 1966]
• Special light-weight fan with four aluminum blades [only the blades were aluminum. The important feature was its light weight.]
• Special water pump impeller for high rpm operation [not mentioned. Impeller's reduced number of vanes reduced water cavitation at high rpm.]
• Special fuel pump for high rpm operation [capability was normal. The extra spring helped the lever follow the eccentric at rpm without bouncing.]
• Heavy-duty damper with separate extra counterweight [yes, the damper was thicker, but the timing chain/gears w/hatchet weight is meaningless. They just supported the extra counterweight.]
• Special high nodularity crankshaft [missing. big item.]
There was no such thing as special mufflers for a hi-po. Once GT's started being built, A code GT's shared the same exhaust as a hi-po (no matter if the hi-po was a GT or not)
Keep it comming. This feedback is great. I hope I'm not the only one still learning!

Not quite true, the hipo exhaust was unique in the manifolds and h-pipe.... but I'm sure you know that, lol
I think Charles was refering to the exhaust system BEHIND the manifolds. Not from the heads back. And the H-pipe was subtly different, but there is a difference, I understand.<img src=images/icon_smile_big.gif border=0 align=middle>

Didn't the A code GT cars have an H-pipe as well, or was this a K code only feature?
Yes, the A code GT cars had an "H" pipe unique to the A code GT only.

Couldn't you order dual exhaust as an option on any V8 engine?

When I ordered my 66 Fastback in January of 1966, the only engine that was factory equipped with dual exhausts as an option was the 'A' code. The 'K' codes came with duals as standard, the 'C' code could not be ordered with duals. In 1964, the 260cid engine did not come with duals either. I assume that in 1965, the policy was the same as in 1966. No telling what dealers did though.

According to the Ford parts catalog, there were many Mustang dual exhaust systems. The 289 HiPo was the first with a transverse muffler until October 64. Then the Arvinode system came out for the HiPo. There was also an option (called a "Performance Image Option") for the A-code which was the Arvinode system. The Arvinode system was dumped in favor of oval mufflers in April 1965. The GT came out duals as well. By the end of 1965 you had the 289 HiPo, GT (All A-codes), and optional duals for A-codes. HiPos had the unique H-pipe to connect to the HiPo exhaust manfolds, and the GT had the trumpet tips. Performance Image Option also shows trumpets. Looks pretty similar for 1966.
