You can stroke the 289, you may have to call the supplier as they don't always show all applications. I had a local reputable shop do mine, the block was already bored to .030 and to clean it up we had to go .040" so i now have a 333 c.i. I used KB pistons and Scat cast crank/3.25" rods with AFR 165 58cc heads. I haven't installed it yet but I expect it to run like a raped ape compared to the 200HP stock I had.
The shop barely had to notch the bottom of the cylindersleeves to clear the rod caps, I also added an FMS windage tray, just needed a dent to clear one rod cap. I didn't want to push the motor closer to the edge by going 347 as the rod angle gets more excessive and I want this motor to be daily driveable and last 100K+ but be capable of some 1/4mi. and road course fun.
If you're building it yourself do a lot of research, figure out what cc the heads are you'll be using so you can match your pistons up for whatever compression ratio you're shooting for. I ended up with 9.6:1 as I wanted to be between 9.5 and 10 so I could advance my dist. for racing and retard it to use 87/89 for highway driving. If you're going to let a shop build the shortblock at least, I'd sit down with the builder and discuss what you're going to use the car for and they'll help you narrow down the cam and comp. ratio you should use with all your factors (
trans., rear diff. ratio, etc.). I first used CompCams free camquest program to narrow down which cams I was interested in, settled on the XE262 since I'll be using PB and A/C, I listened to a friends 268 and it was too lopey for me, he also lost vac. at that grind. The Camquest is a neat program as you can change variables (diff. ratio, etc.) and rerun it to see what effect it has on the overall.
The 289 is perfectly useable in my book and I really prefer using my original block as most of the cars around me all have the later model 302, I like being different and squeezing potential out a 'little 289'. My block, heads, intake will all be painted stock ford blue for a little sleeper edge.
If you have any questions on my build drop me a PM.

EDIT: Oh man I just noticed, Chris; did you drag this up from 2006?

Is there a stroker kit for the 289 Block?
