Ok ..new project beginning asap. I am building a 390. I need to get as much torque as possible . What machine work or mods can I do or parts can I add to achieve maximum torque from this engine? It will go in a half ton truck that is used for hauling wood,construction equipment, and recreational vehicles as well as trail driving. I believe the r/p gear ratio is 3.50 and it has a manual np435 transmission. The heads are stock D2's Thanks all.
