289 vs. 302 stroker

i got a old 289 and when i rebuild it i want to give it a little more kick and ive heard that the 5.0 is the design as the 289 and ive found out it has the same bore but different stroke does that mean i can add a 5.0 stroker kit to my 289 and if so will a 347 stroker work?

According to a few sites I seen they make stroker kits for the 289 - 302 into a 347. But unsure of most ford stuff, I`m a GM guy. honestly, why do this? who not go with a 351 windsor? it`ll likely be cheaper, and the cost of most 351 parts are the same as 302 parts. and from what I`ve seen, 351`s make real nice power.

i think it would be cheaper to go with the 347 stroker, from what i have heard getting parts for the 351 is harder and more expensive. later

347s have a lighter rotating mass than 351, therefore will rev faster. 347s are also smaller and lighter than a 351, i would think that a 347 would cost more to build than a 351 of similar output....but i could be wrong.

I think the reciprocating assembly alone would cost more for the 347 than the build up for a 351. Also, even though it's not much, the 302 block has a slightly longer cylinder wall (in the crankcase) so I would check with the stroker people prior to installing one in the 289. Besides if you drop those bucks for the stroker, you might as well just start with the 302 block.

I'll be firing up my new 331 tomorrow. I started with a Mexican 302 block and a kit from SCAT (crank & H-beam rods, SRP pistons).

Some people prefer the 302 for the reason that Woodz stated. Others say a 289 will work fine.

If you decide to go 302 block, you might also consider whether or not you want a later model roller cam block.

It all depends on what your goals are and how fat your wallet is.

I have a 66gt with a 289 that is close to 400hp. It will twist tight all day long. Why not just rebuild your 289 and build it right. Just a thought.

What's your combination? That a decent amount of power from a 289.

The engine looks stock exept for the Thorley tri Y's. HiPo heads that have had some magic worked into them. An origional Shelby intake that was installed at the dealership(yes I have the paperwork). That has also had some magic worked on it. Good pistons, rods, crank.etc. Holman Moody cam.There are a few more tricks to it. If you need more info let me know.....Iwill pm you

I did not build the engine but have talked to the guy who did. It was done 8 years ago and he could not remember all of the specs,but he did say that alot of tricks were used in the top end and some in the bottom end. I know that does not help much, but trust me the car rocks and rolls. Take a look at this. I imagine some of the same tricks were used. Oh yes one more thing, the guy who built the engine workad for Roush racing when the engine was built.http://www.mustangandfords.com/techa...898/index.html
