Lately I've been wondering the axle ration on my truck. Its a 94 C (That's the 2wd truck) with the Silverado trim and 350 (5.7). Does anyone know what it would be or how I could tell?

One way is by looking at the size of the tire. As ageneral rule (not set in stone) 265's had a 373 or 410, 245's had the 342.....

I didn't think they got 265 until the Vortecs were put in? Anyhow I've got 235, but I thought it may be a 3.73 or 4.10 because its the work truck so its made for towing and hauling. Its amazing how a single cab long box is still longer than almost every other vehicle out there.

If it's the plastic interior work truck with a short bed I'd wager it's 3.73. IIRC you had to special order 4.11, but stand to be corrected. My old man would order 3-4 new work trucks every year back in those days and they were long bed, 2wd, 4.11 gears. Those things could really smoke the rear tires. :)

1500, 2500 or 3500? Manual or auto? I have the '92 Chevy Trucks brochure in front of me with the info.

Auto, 1500, Long box, single cab, 350, weren't they all plastic interior? Yeah, he used to carry a lot of wood and stuff and always had extra leaves put in so he could haul more.

Check your RPO codes, they should be on the drivers side door or in the glovebox. Fullsizechevy.com is an awesome site for the 88-98 GM trucks.

Well, if I read it right I have the 3.42.....but I'm really surprised about that one.
