Hi everyone just picked up a 13' Boss #3205. So far have been loving the car compared to my old 14' GT. Just threw on a mcloud clutch, flywheel and ford racing short shifter. Only issue Ive been having since I picked the car up is below 2K RPM I get a slight high pitched squeak sound almost like a turbo spool type noise if I am under load (about 40% throttle ). It doesnt make noise if im just slightly on the gas or when Im really burying my foot in it at 2K rpms just at part throttle. It seems to go away past 2500 and up but it most prevalent below 2K.Thinking it may be a vacuum leak I checked over the hoses and clamps on the intake and everything seems to be fine. It does have the side exit restrictor plates off but I am not sure that would be the cause? Any help would be appreciated!
