Upgrading My 350 to a 383 Stroker - Need Some Guidance!

Introduction

I’ve been toying with the idea of converting my Chevrolet 350 engine to a 383 stroker for a while now, and I’m reaching out to gather some insights. It seems like a popular upgrade for performance enthusiasts, but I want to make sure I go about it the right way.

Why the Upgrade?

The primary reason for considering the 383 stroker is the potential increase in torque and horsepower. I’ve read that this could significantly enhance the driving experience, especially for someone like me who enjoys a bit of fun on the road. Can anyone share their experiences with this swap?

Components Needed

I’m aware that the transition from a 350 to a 383 will involve more than just throwing in a new crankshaft. Here’s what I think I might need:

  • Crankshaft (of course)
  • Pistons
  • Connecting rods
  • A new set of camshaft specs
  • Possibly new heads to match the newly increased displacement

Are there any manufacturers or specific products you would recommend? Also, how crucial is it to balance the engine after this upgrade?

Installation Process

I’m considering doing this myself, but I’m not entirely sure I have the experience necessary. How complicated is the actual installation? Would it be advisable to have a mechanic or a friend assist me? What are the typical pitfalls that come up during the swap?

Costs Involved

And then, there’s the budget. What can I expect to spend on this project? Are there ways to save costs without cutting corners on quality? I’d love to hear your numbers if you’ve done a similar conversion.

Performance Comparisons

Lastly, how does the performance of a 383 stroker compare to a standard 350? If anyone has done side-by-side comparisons, I’d love to hear about not just the numbers, but also the real-world driving differences.

Thanks in advance for any pointers you can provide! I’m looking forward to diving deeper into this project and making my ride even more exhilarating!

Upgrading from a 350 to a 383 stroker is a great choice! Just ensure your block can handle the power increase. Check for any cracks and consider the strength of the cast iron or aluminum block you’re using.

3

Good point! I’ve heard that block strength really varies. What crankshaft options are you considering? Trying to match the stroke could be a challenge.

4

For sure! Going with a 383 means you need a compatible crankshaft. I recommend a cast steel crank for durability. Are you leaning towards a specific brand?

I’ve been looking at Eagle and Scat cranks. They’ve got good reviews! Anyone have experience with them?

6

Eagle cranks are solid performers! Just watch out for balance issues; you’ll want to ensure it matches your setup. Also, don’t forget about the compatibility with existing drivetrain components!

7

Right, drivetrain compatibility is crucial. Has anyone retrofitted a 383 into a vehicle that originally had a 350? Any surprises?

8

Yep, I did that swap! The biggest surprise was the need for a new transmission converter; the 383 requires something that can handle the extra torque. Make sure to plan for that!

9

Good to know! What about the headers and exhaust? Will I have to change those too?

10

Headers might need to be changed if you want optimal flow, especially with a 383! I went with long-tube headers for mine, really opened it up. How’s your exhaust system currently set up?

I hope this doesn’t lead to a header war about long-tube vs. shorty! Either way, fitment is key with the 383. I just want things to bolt right in!

12

We all do, but with a build like this, it’s more about working with what you’ve got! Keep that in mind and you’ll do great!

13

Upgrading to a 383 stroker can yield significant performance gains! You can expect around 50-100 more horsepower and similar torque increases compared to your stock 350. Just make sure to upgrade your fuel system to handle the extra demand!

That’s exciting! Have you thought about what kind of tuning you’re going to do? A good tune can really maximize those gains.

15

Don’t forget about the exhaust! A good aftermarket system will help you get those extra horses out and improve sound. The stock setup is usually too restrictive for a stroker engine’s potential.

16

Exactly! Also, make sure to consider the intake manifold and carburetor. They really impact how well the engine performs with increased displacement.

17

A 383 is a great choice! You’ll love the low-end torque, especially with the right camshaft. Think about what kind of driving you’ll be doing most of the time, like more street or strip.

18

Totally agree! And while you’re at it, maybe upgrade your transmission. The stock one might not handle the increased power effectively.

Is the 383 stroker engine worth it? I mean, it sounds great and all, but is it going to affect reliability? I’d love to hear some thoughts.

You raise a good point, omarwarren. I think with the right components and tuning, a 383 can be just as reliable as a 350. It’s all about quality parts and proper installation.
