Anyone Upgrading to a Chevy 383 Stroker Crankshaft? Need Some Insights!

Good point, @xwarren! I forsee a lot of people underestimating that! If you don’t upgrade the fuel pump and injectors, don’t expect great performance.

While I’m all for the upgrades, don’t forget about emissions. Some states have strict rules, and a stroker might raise a few flags in terms of legality!

Haha, nothing like passing off a stroker crank to the emissions guys! But seriously, good to keep that in mind, @robertoclements. Always better to be safe than sorry!

I’m considering the 383 stroker upgrade, but I’m curious how much torque it really adds. Anyone have real-world experience with this?

I recently installed a 383 stroker, and I saw a noticeable increase in torque. Expect around 450-500 lb-ft depending on your setup. Pair it with better heads and a cam for maximum gains!

A great topic! I’ve heard that tuning is crucial after upgrading to a 383. What are your tuning recommendations?

Definitely get a good dyno tune! It revolutionizes your drivability and maximizes performance.

I’m excited about the horsepower gains! I’ve heard varying numbers; what should I realistically expect?

With a 383 stroker, many report gains between 400-500 hp. It depends on your additional mods like headers or intake!

I want to boost performance but keep my ride enjoyable. Are there any suggestions for affordable complementary upgrades?

Upgrade to a high-performance carb and consider an aftermarket ignition system! It’s usually worth the investment!

Is there any downside to the 383 stroker? I’ve heard it can affect idle quality—any truth to this?

It can, especially with a big cam. Some people love the lope, others find it annoying. Keep that in mind for daily driving!

Haha, so you might end up with a car that sounds like a beast but idles like a cat! That’s a tough choice. :smile:

Exactly! But hey, it’s all about what you want from your ride. Performance or a smoother ride? Pick your poison!
