My 96 only had 1 airbag actually with those cupholders. Only way I can tell the 95 and 96 apart without popping open the hood was to look at the redline. 4500 on the 350 TBI and 5k on the Vortec 350. No clue on the 305s though. I don't mind gearing down when pulling a load, but that thing will struggle to pull 5,000+ lbs at highway speeds.
My Camaro is a 73. Progress has been pretty slow lately though.93 Suburban (Southern Slayer): TBI 350, 4L60E

I just drove to and from St David, AZ from Las Vegas, NV and I got great gas mileage in my 4x4 z71 burb. How is that possible I get better gas mileage in this vehicle than in my S10 blazer? It's so awesome to get that kind of mileage so both me and the wife were impressed.What do you have in your garage?

BUT, with the added weight of my truck, the 5.3 has extra power to balance it out over the 4.8 and the 4x4 shouldn't cause that much of a decrease, so I think gear ratio and the increase in rpm at any speed has a huge effect on fuel economy. It also changes the performance drastically. With 4.10 gears, the avalanche is better off the line and better for towing than the 3.42s in my silverado, but when I go to pass people on the highway I don't have the power with the 4.10s. The silverado with a 4.8 and 3.42 gears would run 100mph+ in second gear and pass people now problem with quick highway acceleration. The Avalanche with 4.10 gears is slow to accelerate on the the highway and takes more time to pass people.
