cobradave before you change the cam, Check the basics first. Put new plugs in the car and go for a normal drive. Get the motor to operating temp. Shut the motor off and let it cool off and check the spark plugs for color. They should be a medium gray. If they are black you have a fuel problem,EGR problem, or carb problem. What is the fuel pressure regulator set at, with and without boost. Check the float levels, they maybe too high. Egr maynot be seated causing a vacuum leak in the motor maken it run rich. What ignition are you running?? What is the base timing set at. Put a vacuum gauge on the motor and see what the reading is?? Should be 16 to 19 inchs and a steady needle. If you are still having a problem go to a Dyno speed shop that has a air/fuel meter to test the motor. You maybe jetted too big. You need to be rich but there is a limit. Check the basics first than E-mail back if you have not found anything wrong with your car. Rick Lake
