Make sure to keep a clear diagram or label your wires as you go. It saves a lot of headache and confusion later!
Exactly! I think I’ll create a wiring diagram this time around. Thanks!
Reflecting on these issues, it’s amazing how one small mistake in the firing order or wiring can lead to a cascade of problems. Always check your work!
Hey everyone! The firing order for a Chevy 454 is 1-8-4-3-6-5-7-2. I found it crucial when doing any modifications to maintain that order for optimal performance!
That’s right, qlopez! If you’re considering upgrades like a performance camshaft, be sure to check how it might affect your firing order and the overall timing.
I’ve done some mods on my 454, including an aftermarket ignition. It really brought the engine to life! Just pay attention to the wiring; it can get tricky.
Interesting point, tammyperez! When you’re tuning, what’s your strategy? I’ve found that incremental changes can lead to better reliability without huge jumps in performance.
For sure! A balanced approach when tuning works best for me too. I tend to use a wideband O2 sensor for fine-tuning my mixtures.

Great advice, veronica63! I’m curious, how do camshaft upgrades specifically affect torque? Thinking of a new grind for my engine.
A new cam can shift your power band, usually adding more torque lower in the rev range! Just remember to also consider your headers and exhaust system.
I’ve had mixed experiences with headers. Some gained power, but others caused headaches with fitment issues. What brands have you all had success with?
That’s a real dilemma! I had good luck with Hooker headers. Perfect fit for my 454, and they definitely improved performance!
Honestly, what is it with modifications that lead to issues? It’s like they come with a warning label: “Modifications may cause unexpected headaches!”
Haha, so true, lisa65! The struggle is real! But when it all comes together, nothing beats that feeling of cruising with a finely tuned 454!
