Just wondering if there are any reputable online sites that sell performance parts for a grand marquis. I am looking to take my 97 LS and put on a small super charger and other basic upgrades. was looking at flowmaster 40's for exhaust. would a 97 SVT cobra supercharger work with my 4.6l?
well i am pretty sure that the motor that is in the marquis is the same motor that ford put into the mustang GT 4.6 liter over head cam i am guessing that you might have to change the intake manifold and you would need to have your ECU tuned for the supercharger put if the engine in the cobra is a 4.6 i dont see where it would not work...
