I did an exhaust upgrade using Flowmaster, and it sounds amazing! Plus, it gave me more torque in the low end. Highly recommend, especially for towing!
I installed an Edelbrock intake manifold, and the difference was incredible! I gained about 20 horsepower after tuning. Worth every penny.
Just remember, don’t forget the tuning after mods! It’s crucial for getting the best results. Has anyone tried any specific tuning software?
Yeah, I used HP Tuners for mine. It was a bit of a learning curve, but it really let me tweak things perfectly. Definitely a smart move post-modification.
I actually just tried EFI Live, and I was blown away by the results. It’s super user-friendly and provides robust adjustments!
I’ve heard of some people doing cam swaps for the Vortec 350. Does anyone want to share their experience with that? I’m curious about the power gains.
The cam swap can yield significant results! I went with a mild cam, and I saw a big improvement in my horsepower curve. Just be prepared for a slightly rougher idle.
That’s true! My truck has a little more growl now. Definitely ups the excitement level!

What about headers? I’ve read that they can improve exhaust flow significantly. Anyone has them installed?
Totally agree! But be careful with emissions laws in your area when installing headers.
True! I’ve heard some guys running into trouble with emissions. What about upgrading the fuel injectors? Any recommendations?
I upgraded to larger injectors, and it kept my air-fuel ratio right on point after the mods. It’s vital to pair these upgrades. Just make sure they’re compatible!
Exactly! Compatibility is key. I once overshot the injector size and it caused some hiccups in performance; always check specs first.
I’ve owned a '98 Vortec 350 for over a decade, and I can say they are quite reliable engines! Just make sure to keep up with the oil changes and monitor the coolant levels.
That’s great to hear, April! I’ve read that the intake gaskets can fail over time. Has anyone had experience with that?
Yes, jmartin, intake gasket issues are common after around 100k miles. It’s a good idea to replace them proactively if you’re starting to notice any leaks.

I’ve dealt with the leaks firsthand. It caused my engine to overheat a few times! Always keep an eye on the temperature gauge and consider better cooling solutions if you plan to mod.
Good tip, ryanreyes! I’m doing some mods soon and was wondering about preventative maintenance. Any recommendations?
Definitely! Regularly check and replace the fuel filter and spark plugs. It makes a huge difference in performance.
I’ve had this engine misfire sometimes, so I’ll give that a shot. Anyone else replace the camshaft? Curious about the difference it made!
