Well after having to buy a new radiator for my z it came today and it got installed and she is running again, now all that is left for the engine at this point it a oil change(1 year old oil as far as i can tell ewwwww), and have to get the 72 thottle arm as the 74 just dont cut it with the 72 carb linkage, also the float bowl vent nipples? the ones that go to the air cleaner what size and thread type are they i dont have them on my car..... good thing this car came to me for free....

anyone know the answer to the float bowl vents?
