ok back to the ?..if this is the engine you have to work with.....shaving the head,port and polishing it and bigger valves with a header and intake with a 2 bbl holley will make if fun to drive so done be scared to be different

2000GT4.6

My friends car (well he doesnt have it anymore) had a 289 that said "Hi-Po" on the engine. I beileve it was on the air cleaner. Also the VIN said the car came with a HiPo. So unless someone swapped out the engine for a regular 289 and kept the air cleaner I am guessing it is a hipo.

I dont think it was much of a conservative (at all) 271 HP. That car was slower than ****. With 271 HP it would (should) walk a stock 04 GT (they didnt wiegh that much did they?). As I said, I walked it (hard) with my stock slowbox thunderbird 5.0 (low output).

Maybe he didnt have a HiPo and someone built a faker, I dunno. We never did anything with the engine (it was his dads, won it in a raffle) so I have no idea. I am not familar enough with the 289 to tell the difference by opening the hood. In any case, I dont think 46 more horsepower would have helped out much.

As old as the car is, I dont think he is going to spend much more on a 351 install than a 289. Most of the stuff should bolt up, or be made to bolt up with some junkyard (cheap) parts. I would agree with you if we were talking about a newer car. If he is looking for performance the 351 will beat it hands down on a horsepower/dollar ratio.

BTW sratchy, if he is concerened with fuel milage he shouldnt have bought a mustang to begin with, and he wouldn't be looking at the problem from a performance point of view. This is my entire point.

Performance : 351
Stock look/value and milage (i guess, still will be crappy MPG) 289

2000GT4.6

Also if he wanted to get insane I would imagine somewhere somebody makes a turbo kit for these things.

I still dont think your going to get much performance out of it (with engine work etc no FI) , even if you build the engine. There just doesnt seem to be much to work with here.

You are casting your opinion about the 289/271 to use your quote "that everyone seems to talk like they are something special", on a HiPo air cleaner can be had for $19.95 on Ebay?. I had one on my 66 fastback in 1972. It wasn't a HiPo but the decal made me feel good at the time. Also, if it was an original "K" code car I doubt it would have been raffled, they are worth big bucks. If it had solids, you'd know because of the unmistakeable sound and the fact that you would be adjusting them quite regularly. As I said it is a special motor and those that know them understand. Mr. Shelby would not have used it for the small block Cobras if it was a dog.

With regard to dollar per dollar performance, you are spot on. The 351 can make more horsepower and does fit quite easily and it were my car, in lieu of a stroked 302, thats the swap I'd go for. For ease of conversion, the 289/302 is the way to go.

MustangCavron66, you can do a lot of things, I first recommend, buying a Falcon Performance book, I think I bought mine at fordsix.com It gives you ideas, you wouldn't of thought of. First headers will help, then a bigger carb, I think someone makes an adapter for a 2V. Switch the heads from the 250 onto your 200. I would send you mine, but I just moved, and I can't seem to find anything (my mustang books, and such). A bigger cam could come in somewhere in there. Everyone seems to under estimate the inline sixes, the have a little more potential than what is thought. I like mine, but I am also feeling the need for a V8.

289 vs 351 hmmm... 289 parts are mass produced as well as the 351. Parts for parts, a 289 doesn't match with a 351 its like comparing a fat chick, to a super model - one has beefeir parts and out weights the other, and one can move slickly and will keep you wanting more. A 289 will fit better in a car with a inline 6 better, than a 351, along with the 289 fitting the orginal transmission, excluding the bellhousing. The 289 would get my vote ( maybe because I want to put one in my car?)

are you guys talking about a 351 windsor? i'm thinking about rebuilding my 289, but i was also thinking about buying a 351, but i already have a new intake manifold and a new cam for my 289, they won't work on the 351, will they? How much could i pick up a 351W for?

MustangCavron66

thanks Sprint that helps out alot. But i just got the mustang, and its not exactly up to par yet. Its been sitting in my cousins drive way for a couple years now, and besides the obvious cosmetic stuff that needs to be fixed, what are the basics that i need to check for, to get it back up to par? (under the hood im talking about).

I new here but a 351 is a good truck motor. A 289 is a block to block motor. You have to build them to make them fast. Fords cost a lot of money to make them fast, but they are fast. A stock 289 is a dog. My car will eat up a stock GT. A 351 is to big for the front-end. Those stock towers. So I hear. A six is a great little motor. Keep it. You can do a lot with them. Duel exhast, head job, Turbo, Bigger carb. All of this is great but a stock car needs less work. You spend less money and time with it. If I was you , I would keep it stock. Is it just me or do those sixes sound neat?

I also have a 289 in my 66 mustang, it needs alot of work but it is the original engine. I was urged to go with the 302 Stroker crate engine and my understanding was it would bolt right in and have extrodinary horse power. Any opinions on the stoker 302?

Try going to www.fordsix.com. Those guys know how to hook up sixes! As far as a 289 not having power, with the right combo of cam/carb/intake/exhaust 300+HP is possible.
