Looking to Learn About the SBC 427 Crate Engine

Rodney, the C10 has a bit more space. You may just need a heavier-duty radiator to keep it cool, but it should fit well!

This all sounds fun! What about wiring? Is there a recommended harness for the SBC 427?

For wiring, I suggest using a universal harness if you’re not going for a factory-style look. Makes things easier and cleaner!

Good tip, iharris! I would still recommend checking local regulations if you’re in an area with strict emission laws.

Anyone have issues with fitting the air cleaner due to hood clearance? Curious how that went for you all!

Holly, I had a slight problem with hood clearance on my Camaro. I ended up going with a drop-base cleaner that did the trick!

That’s clever! I didn’t think of that. Did it affect airflow much?

Not really! It actually helped with performance. But I can’t guarantee that for every setup, though!

I’m glad to see interest in the SBC 427 crate engine! They’re known for their power but regular maintenance is key for reliability. I recommend using high-quality oil and checking it often.

Absolutely! I’ve found that keeping the cooling system in check also makes a huge difference in longevity.

I’ve been running a SBC 427 for a few years now, and I’d say one common issue is overheating if the cooling system isn’t up to par. Regularly flushing the coolant helps!

That’s really helpful, jpitts! Is there a specific coolant you prefer? I’ve heard mixed reviews about the standard stuff.

Great question, simpsonjanet! I usually stick with a 50/50 mix of distilled water and antifreeze. It’s done wonders for cooling efficiency in my experience.

Sounds good! What about oil change intervals? Different opinions on that…

For oil changes, I usually do 3,000 miles for conventional oil, but if you’re using synthetic, you might stretch it to 5,000-7,000 miles. It really depends on how hard you drive it.

Exactly! Also, don’t forget to check your filters regularly. A clogged filter can cause serious issues. Maintenance is not just about oil!

Good point, Karen. Speaking of issues, has anyone had trouble with their spark plugs? I’ve had mine foul out too quickly.

Yes, spark plugs can be a pain! Make sure you’re using the right heat range. Sometimes a too-hot plug can cause fouling. I’d check the gap too, just to be safe.

That’s really insightful! Curious, any tricks for cleaning them? I hate replacing them too often.
