Hawk, I'm looking for the early aluminum PI Intake with the oil filler tube. I beleive the casting number is C3AE 9424F or the C3AE 9424E, or the C4AE 9425G. Reason I would like to go with these manifolds is for the oil filler tube provision. I have a Performer and a Streetmaster but neither have the provision for the oil filler tube. I wanted to keep the baldy valve covers I'm currently running. Just looking for options.
