I have an opportunity to swap my 350 4 bolt main for a sb 400. Would this be a good trade? I know I can get more torque & hp out of a 400, but is it a reliable engine? Will it get crapper gas mileage than a 350? The 400sb is currently in a 75 blazer. Seems to run pretty strong. Let me what you guys think.
