Performance & Modifications

I’m diving into the world of the Ford 289 engine and I’m curious to learn more about its bore and stroke specifications. From what I understand, the 289 has a bore of 4.0 inches and a stroke of 2.87 inches, which gives it a pretty decent power output compared to other small-blocks like the 302.

Here are a few things I want to explore:

  • Performance Capabilities: How does the 289 stack up against more modern engines? Are there notable performance enhancements that can be made?
  • Modifications: What upgrades are most effective for squeezing out more horsepower?
  • Comparative Insights: How does the 289 compare to the 302 in terms of modifications, ease of tuning, and overall performance? Is it worth considering a switch to a 302 if I’m looking for more kick?

Questions for the forum:

  1. Enhancements: For those who’ve modified their 289s, what upgrades did you notice had the most impact?
  2. Community Experiences: Any thoughts on whether sticking with the 289 or upgrading to a 302 was the better long-term choice?
  3. Technical Details: Are there any hidden specs or features of the 289 that I should be aware of that could influence my upgrade plan?

I’m looking forward to hearing your experiences and insights. Thanks in advance for your help!

Many classic Ford cars like the Mustang and Falcon utilized the 289. Its compact size makes it easy to fit in various engine bays too.

I’ve seen people swap it into older models quite easily. Such a great engine for projects!

Definitely a popular choice for hot rod builds! But I’ve read that some might prefer the 302 for more power. Any thoughts on that debate?

That’s true, but the 289 has a unique charm, and its rev-happy nature is something the 302 doesn’t replicate.

The Ford 289 definitely deserves a spot in engine hall of fame, right next to its buddy the 302. Can we all agree on that?

I’ve been working on my 289 and noticed that increasing the bore can really help with airflow. Overboring can potentially unlock some serious horsepower.

Definitely! I’ve heard that a stroker kit can also pair well with a larger bore to maximize torque.

For the 289, I recommend matching your mods with a decent camshaft upgrade; it can complement the bore and stroke increase really well.

What kind of cam are you guys using? I’m curious to see if there’s a popular choice among you all.

I actually went with a Comp Cams camshaft; the improvement in responsiveness was noticeable! How is everyone’s experience with ignition upgrades?

I find that tuning your carburetor is just as crucial as bore and stroke upgrades. It makes everything else work better together!
