Old Advance Design series Chevy pickup trucks are not really in my wheelhouse, but if I'm reading the signs right, the vent windows, pushbutton door handles and hood badges mark this Emerald Green example as a 1952 model.
That means it has a slightly undersquare Thriftmaster 216 cubic inch OHV inline-6, burbling out 92 SAE gross horsepower... which would be sixty-something in modern SAE net terms ...at 3400 RPM and 176 lb-ft of torque at 2000. The power ratings are absurdly low by modern standards, but remember we're talking an engine with a single sidedraft Carter 1V carb and only a 6.6:1 compression ratio.
