Ok I swapped motors in my car I have a 91 gt I put a 93 by motor and computer in my car. The motor is bored .30 over with trickflow heads and a gt40p intake, e303 cam shorty headers. Now it still has the stock air intake, throttlebody, and maff. I Dyno it it only making 226hp and 311tq. It runs good but I know it not nearly as fast as it should be. I was told I need bigger maff and throttle body and 24lb injectors but I should have more horsepower then that! Any help is greatly appreciated
