I just in the beginning of swapping my 305TBI to a 350TPI-89 and wounder if the chip to the 350 ecm are stock,it is a DELCO APYU 3516 chip.
And does any of you running a aftermarket chip whith any improvment or is it only a costumchip that will work.I am going to stay close to stock on my 350 just headders and 3"full exhaust.
