I wonder how much torque the standard 350 sb has got? I cannot figure out from my papers how much torque my '79 Blazer with its 350 sb has stock. Also since I added a 500er Edelbrock carb, performer air intake manifold, performer camshaft, flowtech headers and 2 1/4" dual exhaust system I feel the engine pulls much stronger, but in summary what did I gain? More horespower or more torque? Anyone can tell?
