I just bought a donor car to get the pillars, and it came with a 289 in pretty good shape. I'm thinking about reusing the 289, but it definitely needs a rebuild. I figure it needs a boring, or at least the ridges reemed.

ok, i dont profess to be expert, but I was told to avoid overboring 289 any more than absolutely necessary as they are fairly thin walled.

the main problem is that they become harder to cool.

you're lucky if you have found a good 289 to start with. they are rarer than rocking horse poo over here

I havent heard that Aussie, thanks, I'll keep it in mind. I guess if it can be freshened up and machined to work without overboring it, then theres no need. I was just curious.

Plus if you only bore it .10 over, in ten years you can bore it again and still be safe.

Do the math - 4.030 (the bore) divided by 2 - that number times itself - times pi, 3.1416 - times 2.87 (the stroke) - times 8 (it is an 8 cylinder car, right?) and your answer is -
Remember all that crap they taught you in school - put it to work.

The volume of a cylinder times eight.

I'm officially old, I'm worried about our youth.

BTW, if you look at Jim's formula, you'll see that the displacement is directly proportional to the square of the bore. New displacement = ((new bore^2)/(old bore^2))*original displacement. Keep in mind that your number could be off by 1c.i. due to rounding (hint: a 289 is really a 288.52).
