I have a 1968 mustang California special and i wanna stroke out the original 289, but i cant seem to find any kits to do so.

seeing as you have to literally change every part to build a good stroker motor you should just put the stock engine aside and install a crate stroker motor...aside from that how about just adding a good cam, aluminum heads/intake and exhaust? That will get that pony galloping faster

302 stroker kits work and everyone pretty much uses those. 289 stroker kits aren't widely advertised because 302 blocks are what is used more. I'm using a 331 kit on my 289 bored 0.20 over.

Same here, stroked my 289 out to 333ci (.040), I'll have to dig my paperwork out to check the part #'s. I preferred to use the original block if it wasn't past .040", you don't see many '67< that haven't been swapped to a 302. I look forward to some 1/8mi & 1/4mi. passes against some similar roller builds to see if there is any great advantage.

Most builders will advise to stroke a 302 instead of a 289 due to the extension of the cylinder wall at the base on the 302. The 289's are known for piston slapping because they lack this bottom cylinder wall support for the pistion.
something you should consider

289 blocks are STRONGER than 302 blocks and are the best block for a stroker . go to a 347 stroker it costs the same as a 331 and will make more power ........... there is no replacement for cubic inch displacement
302 stroke is 3.00" and the 289 is 2.87" .013" could be a problem in some cases.
There are kits on the market that have shorter piston skirting.
289 blocks are stronger than the 302's But I think it's just the late H.O blocks that are considered "weaker"

well i decided to have my 289 pulled out and fixed up but not any huge modification to keep it as close to original as possible, and i bought a 302 roller with march serpentine system ,msd pro-billet , eldelbrock 750 cfm carb , ford racing x303 roller camshaft , crane roller rockers ,bbk shorty header.
would you consider this a good idea?
