I have a 406 and i want to add some more power. What will be the best for the motor NOS, Blower, supercharger? the motor has a carb on it now (eld. 750) and a eld performer RPM. but i have been thinking about buying some vortech heads so i will have to stay with the vortech intake. i really dont have the money to go to fuel injection so what are my possiabliltys for my setup?
