i have a 1972 351 cleveland in a 89 mustang coupe,I have a chance to buy a cintrifical super charger 6 psi for 500.00 but the motor is carburated, is it difficult to arrange that blower to work on a carb motor? the motor is 10 1/2 to 1 compretion and pushing 450 hp. and how much more power should i expect from only 6 psi?
