i have a 90 notchback 306. my question is i have gt40p heads. i have not purchased a set of plus for the motor yet =/..(i just finished pputting her back together). now what i dont understand is when i ask for plugs from an auto store do i ask for an explorer plug? since gt40p's didnt come in mustangs.what should i run in these heads..im an all motor gut with a compression ratio 10 5 1 ..please help me out. another question i have is how do i prime my oil pick up? do i take a cordless drill to my rotor bolt on the distributer,and pop off a valve cover?how can i make sure she's pumping up oil?..any help would be greatly appreciated.
