I have run a 305 on a d yno with a Holley 500. And a brand new Stromberg. The Stromberg pulled better #s up to 3200rpm. . Thi biggest problem with old Stromberg ww. Carbs is the aluminum throttle plate wears out and you can't tune It. Most I find have .020 slop. Then they lean out.. The Stromberg is hands down one of the best old 2 barrels made. I can say from experience. Having owned 30 + gmc v6 trucks..i currently have 3. A 60. A 65 and a 66. I also had a grandfather that owned a gmc dealership until the early 80's. I have hotrodded these. Built one off v6 engines. Currently I have a 384 cube v6 mix of a 379. And the 351e parts. It pulled 285 hp , But best of all just over 420lbs of torque at 1700 rpm. It's running reworked 351e heads. 9.2 compression. Stock points dizzy. And a 351E Stromberg www Carb. Also a single 3 inch exhaust.
