Hello all! I have just become the proud owner of a 66 mustang coupe. The engine code on the plate is K. I know that is a 289 4BBL. What is on the car is a 289 2BBL. what's the difference other than the mainifold and carb? If I replace the manifold and carb will i have the same as what came in the car at 271 HP?
Thnaks!
Jeff

Jeff,
First off, Welcome to Mustangsandmore.com. You have found the best Ford Site on the net. Check out all the Forum's and enjoy.  As pointed out by Scoop, more than likely the "K" code engine has been swapped out. One of the quickest ways to tell is by the Harmonic Balancer. If you have a narrow harmonic balancer, more than likely you have a "C" code engine in your mustang now. The K Codes hade a larger harmonic balancer, a different manifold, carb and exhaust manifolds. There are other differences, but these are the easiest ones to spot. Dave & Terri ------------------

Jeff -Welcome to M&M!No. New manifolds and a carb are not enough. The cam was a more agressive solid lifter style and I believe the heads flowed a little better. Ford also tried to strenghten the bottom half of the engine as well. There are some tell-tale signs that your engine is a "Hipo" 289 (a K code engine). Hopefully someone just swapped the intake... that is wishful thinking though... First, look at the harmonic balancer - it will be wider on a k code than an "A" or "C" code. Under the valve covers, there is a "289" casting. The k codes have two cast dots above the 289. The connecting rod bolts are the larger 3/8" size. The larger bolts required an additional couterweight on the crankshaft (I believe it is external) to compensate for the extra weight (or something like that). The exaust manifolds flow better. I believe the carb it a bit larger as well than an "A" code. Either way, you own a great car! -Eric

Which "plate" are you refering to? If it's the one on the door, those can be bought blank and stamped with anything you want. Check the stamped number under the hood on top of the driver's side fender. That will better tell you what engine the car actually came with. Either way, you still have a good car with lots of potential. Have fun![This message has been edited by 69 Sportsroof (edited 12-06-2004).]

Jeff, welcome to M&M from south central Kentucky.
Another check for a Hipo is look at the lower left corner of the drivers side Head, there should be a small cast number of 19, 20, or 21. Actually the hipo heads did not flow any better than regular 289, only difference was the threaded studs and cast in spring pockets.------------------

Well, as the story unfolds....Thanks to the info from Sportsroof and Mike I have more info that further confuses me! Mike, I can?t find any casting number on the lower left corner of the drivers? side head. But, the engine is still in the car, dirty, and hard to see. I'll keep scraping! On the other hand, I did uncover the VIN on the driver?s side top of the inner fender! It is not the same as is on the door. I am suspect of the door number anyway. It tells me the color was originally Raven Black, but the paint under the seats and around is all blue. I bet someone changed the door at some time with a Raven Black donor... Now, I have a new VIN that is 5F07D174388. I have found out how to decode it and my car appears to be a 65... So... I dont think it's a 66, but I'm still proud!!
Any way you all know that I can look this up and find out the rest of the trim and colors and such?
Thanks for the warm welcomes and all the rapid response! Jeff

It sounds like your fender apron (which is less likely to lie than the door tag) says you have a 1964 1/2 or 1965 mustang with an early low compression 4bbl 289 (210 horsepower). The D code for 1965 was upped to the A code (higher compression, also 4bbl 289). Make sense?I'm curious, now. Does your instrument panel have a sweeping speedometer (1965) or a 5 dial with the speedometer in the middle (1966)? Does your grill have the honeycomb (1965) or the horizontal bars (1966)? Does it have a generator (1964 1/2) or an alternator (1965-1966)?

Hello Daniel! Well that helped too! The spedo is sweeping with the fuel gauge on the left and the Temp on the Rt. Below it is two lights, one is oil and on the rt is Gen.. Also, it looks like a generator on the engine to me. The grill is honeycombed too. On the carb is the Ford tag... it is stamped "C3AF F", then below that in smaller stamping is "C3AD"
So, seems like I have a ton to learn about these things! Sorry for all the questions but I do appreiciate the great answers!

Born in a Ford is right. I did a vin check, and it goes like this:
5F07D174388
the # 5 is the year of the car, so 65
F is the plant where it was built, Dearborn
07 is body style, Hardtop
D means the engine was a 289 4V low comp
174388 was the # built to date
Hope this helps, and make sense.
Oh yeah, welcome to M&M.------------------

Jeff,
Sounds like you actually have a 64 1/2 Mustang or a very early '65. Check around the hood edges. If it has a bevel and you do have a generator in the engine compartment, then you more than likely have a 64 1/2 Mustangs.  Dave & Terri

Soak the engine down with Simple Green and rinse it off with a hose. Cover the carb and distributor with a bag. This will really clean up the engine and help you find the numbers you are looking for. If it has the generator it is definately an early 65 (I don't call them 64 1/2's cause they weren't titled that way, but that's just me...). You should be proud of your find. Sound like you have found the old silk purse in a sow's ear.
