So i had a running 3.8 with no s/c and an s/c one with a rod knock and brand new heads. So i transferred the whole top end of s/c one to my non-s/c. I got it back in the car and it starts rite up however it idles at about 3500 rpm. Any one got any ideas on why?? Exhaust isnt hooked up yet but i dont believe that would cause such high idle. I would appreciate any tips as i finally almost have my gtp done and i run into this problem. Thank you
