Ford 289, looking to stoke and overbore it to a 331

**Also, does anyone know anything about like the Auburn Gears or anything like that? The reason I ask is because if I burnout, only the one tire spins, and I want them to be locked like my cobra so that if I stomp on it, BOTH tires will spin. Just wanted to know the easiest and least expensive way to accomplish this.

From what I have been told, even running a 347 is almost gambling, I was warned to run no more then a 331 or otherwise drop in a 302, 351w, etc.

Yeah, it's just the stock gearing, i never changed anything with it. I'll look it up tell you what the ratio is here in a second if you don't beat me to it.

damn, youll probably beat me to it. Got home late tonight and i have to dance through the rest of the forums before i go to sleep in like 10 minutes. Lol. Let me know and ill dig up some more info during my "study day" tomorrow.

I dunno about taking a 289 to a 331 or 347, but the 302 can be. There's 13ci between the 289 and 302. I know the 289 winds up a lot faster and can sit you back in your seat real good when done right.

As for stroking a 302, you can go to 331, 347, and 351ci of displacement. I would not recommend going to a 351 unless you have a four bolt main and a lot of time and money on your hands to buy the right shit.

You might as well take out the 289 and throw in a worked 302. put the 289 on ebay, I guarentee there are a lot of people looking for one for a true classic or to take a I6 to a V8 without losing too much off the originality.

You can get a 302 with 4 bolt mains and a .030(+/-) overbore from jegs. i recommend the Man-O-War blocks, but they are a touch on the expensive side. From there pick your stroker. The 347 is more of a weekend warrior stroker kit. Not highly recommended for a DD. I see no reason why you can't go out and work up a 302/306 and get a decent number.

I didn't check out the posi thing you were talking about or bought, but I wouldn't buy it myself. I would only buy a true posi rear, even if it costs a little more.

Think this way: You have three options, Fast, Reliable, and Cheap. Pick TWO.

Sorry, it came back to this post when I logged in. :o

The 289 and 302 blocks are identical by the way. They are the same block, the only difference between the 289 and 302 that made up for the extra several cubes is a little bit longer stroke. I got it all figured out already and I dropped the newly finished 331 in it a few months ago anyways, thanks for the reply though. And yeah, I might be getting a true posi rear off a friend of mine here in a bit...Only time will tell, motor runs great though, couldn't be happier.

I'd go with a stroked 302 (I know you are done already). I just flipped thru one of the stang mags recently and they had one (A dart 4 bolt main block) they bored and stroked to about 370 or something like that and made about 650 at the wheels on pump gas. The whole set up the way they did it was just shy of 10K.

You should try to find a 351 if you wanna get a little more power out of it.
