Bruce i know they will bolt right up but i dont know if there was a diference in port size for the 64 aluminum headed 4 barrell 300 vs the 65 models.
Can anyone else chime in with an answer, I'm looking for the driver's side manifold only. If it does not work I'll leave them open for someone else to pick up. Thanks Bruce
The '64 manifolds are different only in that the passenger side one does not have a heat riser valve on it like your '65 does and it does not have the tube in it for the heated choke ('64 uses a water heated choke). If you just need the drivers side one, then it will work just fine. In '66, they moved the heat riser to the drivers side. What I did on my '65 Special is use a '65 drivers side manifold and a '66 passenger side manifold so that I eliminated the heatriser valve and still retained the heat tube for the choke.
