At present I have a Edelbrock Torker Manifold which is a single plane. I was thinking of changing to a dual plane such as a Performer or Performer RPM. Will both of them work under the stock hood or would there be a clearance problem. At present I am running a 750 Holley on the Torker w/o a problem with clearance. Also have a 14" x 3" Air Cleaner.
