Seeking Advice on Upgrading My 351 Windsor

I’m considering upgrading my 351 Windsor with a 408 stroker kit, and I’d love some advice from those who’ve gone down this road before. I’ve done a bit of research, but there’s a lot of information out there, and I want to make sure I’m making the right choice.

Here are a few things I’m looking to understand better:

  1. Performance Gains: What kind of power and torque increase can I expect? Are the gains significant enough to justify the cost and effort?
  2. Installation: Is this something I can tackle myself, or should I look for a professional installer? How complex is the installation?
  3. Recommendations: Are there specific brands or kits that you recommend? I’ve seen a few options, but I want to know what others have had good experiences with.
  4. Related Upgrades: Beyond the stroker kit, what other enhancements should I consider to maximize performance? Do I need to upgrade the fuel system or the exhaust?
  5. Reliability: I want to enhance performance without sacrificing reliability. How has a stroker kit worked out for others in terms of daily driving and longevity?

I’d really appreciate any insights, personal experiences, or tips you have. Thanks in advance for your help!

Absolutely! I’ve seen gains of over 100 hp with the right setup. Just remember, you might want to upgrade the brakes too if you’re adding that much power!

Torque improvements are fantastic with a 408 kit. You can really feel the difference in daily driving. Just curious, though—what kind of vehicle are you planning to put it in?

Great question! I’m thinking about a Mustang. I want that muscle car feel, and a stroker kit should deliver!

Don’t forget about tuning! With the 408 stroker, a good tune is essential to unlock its full potential. I recommend a stand-alone system for best results.

Totally agree! Plus, you’ll likely need to upgrade the fuel injectors and intake. Increased displacement means increased fuel needs!

I’ve installed a 408 stroker in my F-150, and I couldn’t be happier! The low-end torque really helps with towing. Just ensure your transmission can handle the extra power.

Yes! That’s vital. You might need a beefier torque converter. I learned that the hard way!

I love the idea of upgrading to a 408! But, should I be concerned about engine longevity? I’ve heard mixed opinions on that.

11

Honestly, as long as you maintain it and don’t push it to the limits often, you should be fine. Just don’t forget to change the oil regularly!

12

I think the initial investment in a stroker kit will pay off in the long run. You’ll enjoy the performance so much more! Just hold on tight when you hit the gas!

13

Haha, true! Just remember, with great power comes great responsibility (and maybe a speeding ticket or two).

14

I’ve installed a 408 stroker kit on my 351 Windsor, and I can tell you, the biggest challenge is definitely the clearance issues with the stock components. Definitely invest in some quality gaskets!

15

Absolutely! I also had trouble with the oil pump clearance. I recommend using a high-volume pump for a smoother flow.

16

I agree with both of you! Another challenge is getting the right tuning after the installation. Has anyone tried a custom tune?

17

For tuning, I’d recommend going to a professional. I had a DIY attempt that ended up in a lot of frustration. Trust me, it’s worth the investment!

18

I did, and while it worked out fine, make sure to get your fuel system upgraded to support the increased demand. That was my first mistake!

Great tips! Speaking of upgrades, did you all have to change your headers? I ran into some fitment issues with mine.

20

Yes, header fitment can be a real pain! I ended up using aftermarket headers designed for the stroker kit, which made a huge difference.
