Hey there guys am new to the whole foxbody sceen but have been wanting one for years, finaly picked one up last month (89 lx) and now am wondering how modded the car is because it has pep to it and sounds aggressive AF as far ad I know previous owner added gt40 intake upgraded aluminum radiator bbk shorty headers H pipes cold air in take and mds starter cant tell if the heads are GT40 as well but am wondering if there is a way to tell if the car is cammed by its idle rpm or exhaust note?
