I am new to fords. I recently purchased an 89 gt with a 347 stroker that has 192 canfield heads 58 cc milled to 54cc. It has a cobra intake 75 mm tb 1 5/8 equal length headers flowmasters but the car has stock injectors and mass air. Will this be an issue and how would I tune it. It runs good but i hear there is alot left on the table.
