I’m diving into some performance modifications for my 350 horsepower crate motor and I’m looking for some insights from fellow enthusiasts. There are so many options out there, and I want to make the best choices for achieving optimal performance, reliability, and maybe a bit of extra horsepower.

Here are a few areas I’m considering:

Intake and Exhaust

  • Cold Air Intake: Is it worth it for this setup?
  • Headers vs. Stock Manifolds: Any recommendations?
  • Upgraded Exhaust System: What diameter should I go for?

Tuning

  • ECU Reflash: Do I need a tune after adding new parts?
  • Carburetor Options: Which brands are reliable?

Internal Upgrades

  • Camshaft Upgrades: What specs should I look for?
  • Pistons/Rods: Should I stick with stock or go aftermarket?

I’m aiming for a balance between performance and durability, so any advice on what upgrades have worked for you would be greatly appreciated!

Thanks in advance for your help!

If you’re looking to boost your 350 HO, a new intake manifold is a great start. Something like the Edelbrock Performer is popular for increasing airflow and throttle response.

Couldn’t agree more! I’ve also had good luck with a Holley carburetor. It made a noticeable difference in power after I installed it.

Don’t forget about exhaust upgrades! A good set of headers and a free-flowing exhaust system can really let your motor breathe and improve performance.

True! I installed a MagnaFlow system, and it sounds amazing while pushing out extra horsepower. Totally worth it!

What about ECU tuning? I’ve heard that optimizing the map can really enhance both torque and horsepower. Has anyone had experience with that?

All these upgrades are good, but balance is key! Make sure to match your intake, exhaust, and ECU tuning for optimal performance.

I’ve used HP Tuners with great success! It really allowed me to fine-tune for my specific upgrades and got much better throttle response.

I’ve always been a fan of upgrading to a high-performance camshaft too. It gives a great bump in power across the board!

Has anyone tried pairing these upgrades with a supercharger? I’ve been considering going that route for insane power!

I did that once! It was like adding rocket fuel. Just keep an eye on your fuel system to support it.

I’ve read various opinions about headers; some swear by Long Tube vs. Shorty. What do you folks think about this?

Generally, Long Tubes provide better top-end power, while Shorty headers are great for low-end torque. It really depends on your goals!

When installing a 350 HO crate motor, I recommend having a comprehensive toolkit ready. You will need a good set of sockets, wrenches, and torque wrenches. Don’t forget engine hoist and engine stand too!

Absolutely! It’s also essential to have a manual handy to help you with specs and torque settings. Saves a lot of headaches!

One common pitfall is not checking the alignment of the motor before securing it down. Double-check that you’re installing it straight to avoid future issues with driveline angles.
