If I put these GT40X cyl, heads on my 90 LX, can I still use the stock cam, lifters, and rockers? What intake manifold and T.B. size will work best with this set up. Can I use the stock injectors? Thanks, Fritz
Fritz, You can use the Ford Racing GT40X heads on a stock short block with the stock cam, lifters and rockers. I would suggest at least a 65 MM throttle body and the TFS Street burner intake as a good combo. Stock injectors can be used but upgrading to 24 lb injectors and a 70mm Mass Air calibrated for those injectors would be even better, as well as a set of pedistal mount roller rockers.
