Gear Ratio ?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Wanted to see if any of you know what the standard gear ratio would have been in a '68 one ton dually? The only thing we can read on the spid is a 327ci motor. The rest is illegible.
This truck had a PTO winch on it, not sure if that was factory or not. But it had a 327, with 4spd tranny.
We checked the tire rotation method, and came out close to 5:1, then counted teeth on the ring and pinion, and came out to 5.14:1. So we're thinking around a 5.13 gear.
Does that seem right? That is an awfully low gear, even for a 1-ton. With a gear like that, all we can see is needing a 100 gallon fuel tank and a government style bail-out every time we drive this thing.

Thanks
Jay
