Sorta 1 ton. Owned by a welder, there's some serious beef for suspension. She's had a lot more than 1 ton in her :). I did replace the original 2 barrel carb and intake manifold, I did not even know I would need a new cam/lifters. When I did research on cams it seemed like they were for much higher RPM vehicles than mine as far as where they make power. Divulge your knowledge, please!
