I have a '89 5.0 w/ a performance cam, headers, exhaust, and a Cobra intake. I was wondering if it would be good to get 24lb. injectors w/ my setup, because i'm fixing to get a 65mm Accufab TB and a cold air intake and wanted to get a new mass air meter. So do I need to get 24lb. injectors and get a new TB or just stick w/ the 19lb. ones. If I keep the 19lb injectors would I need to get a bigger TB?
