Editorial Policy

These trucks are old enough that bad information costs real money. This page is how we try not to be a source of it and help you fix your rig.

Why we hold this line

The goal of this site is preserving information for the next generation of Chevy truck lovers. These trucks keep getting older, and so do the people who know them best. A lot of what they worked out only exists in somebody’s head, or in a social post that is already unfindable. Getting it written down accurately and keeping it that way is how it survives long enough to help the next kid who buys a 20-year-old Silverado. Everything below is in service of that — a reference nobody can trust is not worth preserving.

Who is responsible for this site

FullSizeChevy.com is independently owned and operated by Todd Grasse in Red Deer, Alberta. Todd oversees the site’s editorial direction and is ultimately responsible for the site and what is published.

The site is supported by a small team handling content editing, video production, publishing, SEO, and website maintenance. We do not use a faceless content agency. Our content is created, reviewed, and maintained in house by people directly involved with FullSizeChevy.com.

How technical claims are sourced

Every technical statement on this site should fall into one of four buckets, and we try to make it obvious which one you’re reading:

• Owner-reported. Something we did on our own trucks, or something the community reported on the forum. Useful, but it’s one truck’s experience — not a spec.
• Manufacturer or standards documentation. Named and linked. If a torque spec comes from a manual, you get the source.
• Calculated. Our tools use documented formulas and verified constants. Each calculator explains its methodology and sources so you can see exactly how the result was produced.
• Unverified. Sometimes the honest answer is “sources disagree” or “we couldn’t confirm this.” We’d rather say that than round it off into a number that looks authoritative.

What we don’t publish

• Fabricated experience. We don’t claim to have done a repair, owned a vehicle or tested a product unless it actually happened. Every repair or modification you see on our YouTube channel is performed on our own fleet of Chevy trucks.
• Unverified specs. Torque specs, fluid capacities, and tow ratings are verified against reliable technical sources before publication. Because incorrect specifications can cause costly damage or create a safety risk, we do not publish unverified figures or rely on a single source when the information is unclear.
• Reprinted tables from other people’s sites. Facts aren’t copyrightable, but somebody else’s compiled table is their work. Where we build a reference, we verify each entry against at least two independent sources and record where it came from.
• Claims about our community. We do not inflate membership numbers, invent history, or claim to be the largest community. FullSizeChevy was once a thriving name in the GM truck world, and we are working to rebuild it into a valuable community again.

How we use AI

We’ll be straight about this, because a lot of sites aren’t.

AI tools are used here for research, drafting, editing and site maintenance. They are genuinely useful for that — they read faster than a person can, and they’re good at catching an internal contradiction across a long article.

What doesn’t happen: AI does not decide what’s true. Technical claims, diagnostic reasoning and anything touching safety are checked by a human against a source before publication. Nothing is published because a model asserted it confidently.

Articles carry a site byline. The person accountable for them is named on the About page.

Safety content and calculators

Our calculators are estimating tools built on published physics and public formulas. They are not a substitute for the instructions that came with your parts.

Every tool shows its assumptions on the page. Every result carries the reasoning, not just a number. And a standing rule: if a device or fuse block manufacturer specifies a wire size or a rating, the manufacturer’s number wins over ours. Where a calculation would produce an unsafe result — a fuse rated above the wire it’s protecting, for instance — the tool is built to warn and stop rather than hand you a number.

Anything involving airbag/SRS, ABS or driver-assistance circuits is out of scope here. Go to service information for those.

Corrections

If something here is wrong, we want to know, and we’d rather hear it from you than leave it up.

Email admin@fullsizechevy.com or reply on the forum. Substantive corrections are made in the article itself and noted with the date. We don’t quietly edit an error out and pretend it wasn’t there.

Money, and what we disclose

Hosting, software and the hours behind this site all cost money, so the site has to earn enough to stay up. Here is exactly where that money comes from — and none of it buys editorial coverage.

• Advertising. The site runs display ads. Advertisers have no input into editorial content and no advance knowledge of what gets published.
• Merchandise. We sell our own shirts, hats and signs. That’s our business and it’s obviously ours — it doesn’t buy a mention in an article.
• Affiliate and sponsored links. Where they appear they are marked, and they carry the appropriate link attributes. A product being linked is not an endorsement unless the article says plainly that we used it.
• Product reviews. If we were given a product, we say so in the review. If we bought it, we say that too.

Our relationship to GM

None. FullSizeChevy.com is not affiliated with, endorsed by, or sponsored by General Motors. RPO codes, casting numbers and model designations are referenced descriptively to identify parts and vehicles. All trademarks belong to their owners.

The community’s content

Posts on the forum are written by their authors and represent their own experience, not a position of the site. We moderate for spam, abuse and dangerous advice. We don’t edit a member’s post to change what they meant.
