Your right on the intake Paul. 2 versions were available. One for the Galaxie and one for the Tbird. The Tbird intake was mlled flat as the engine sat level in the birds. The Galaxie intakes were angled to compenate for the engine angle. But as Paul mentioned the oem intakes are the only game. There was mention in the part of a repop being made but nothing to date. The 3x2 is a way cool system. I've had them and they ran great. Carls Ford parts sells complete setups with new re issue holleys made from the original castings. HP trends has a great tech,tune and rebuild download.
