I am rebuilding a 1988 Unique. It apparently was a factoey demo in 1988 and at one time had a 427 in place. It now houses a 302. My problem the car has a MSD distributor and I am try to add a Kirkham billet puke tank. The distributor is so wide that it hits the tank. Any one have recommendations for a smaller diameter distributor (vacuum advance) that will still fit under the air cleaner?
