Dlampe You are not sand bagging for the Run and Gun are you??
I would start with the exhaust like others have said. You can stick your hand in the turn out and feel that 3" opening? 13.3 is high for street D. When the cam was setup, I know that some cams are made with a 4 degree retard in them. What flywheel are you running? Steel or Aluminium? This will make the motor respond quickier. You may want to run with a A/F meter in the car. Summit has them on sale till the end of August for 3 and change. Alot of guys that are running FE motors have the timing in the 35-38 total when running and all timing in buy 2500 rpm. Mine is 36 with the stock motor. I built a tork motor not HP. I will talk to you later. Rick Lake
