I have a 1977 Chevrolet Silverado that I am restoring and was wondering about the different packages they offered in that year. I was looking at the "Big 10" option and it showed that it had heavier duty suspension to get it just over 1/2 ton capabilities to bypass the emission tests. My truck is a camper edition and had the heavier duty suspension installed also (I don't know if thats a standard camper edition or extra) but does not have the 4 in the 4th digit of the VIN number. Even though it's a camper edition and not a "Big 10", is it safe to call it that anyway since it has the same weight capabilities? Thanks In Advance
Not sure about the camper/camper special editions they had, but the Big 10s also had upgraded front suspension and iirc brakes as well. Kinda hard to read, but this brochure features a tech sheet that lists the some of the specs of the C1500 and the Big 10 (F44): http://brochures.slosh.com (Go to 1977 -> GMC Pickups, scroll to the right until you see the green table)
