I have a stock mid 70's 350 in my '56. It has stoock heads with a 4 barrel intake and a Q-jet carb and dual exhaust. Runs ok I just wanted to get a little more power out of it with out a completed teardown right now..Will putting a dual plane edlebrock intake give me more hp? Should I change outthe Q-jet? Just looking for some cheap ways to get a little more hp with more torque...
