FATSUN Posted March 26, 2011 Author Report Share Posted March 26, 2011 Indeed lots of room do you think the bike carbs or webers on the A15 ??? Quote Link to comment
KELMO Posted March 26, 2011 Report Share Posted March 26, 2011 I think bike carbs because they look cooler (just my opinion). Have you looked on datsun1200.com? Quote Link to comment

Duncan Posted March 26, 2011 Report Share Posted March 26, 2011 Hi can anyone tell me if the a12 head is a straight bolt on fitment to an a15 block .. I *think* they do, but I seem to remember something about checking to make sure you aren't blocking any coolant passages. I believe some heads have them, and some don't. Datsun 1200 dot com is a good place for swap info on that. Quote Link to comment
FATSUN Posted March 30, 2011 Author Report Share Posted March 30, 2011 I *think* they do, but I seem to remember something about checking to make sure you aren't blocking any coolant passages. I believe some heads have them, and some don't. Datsun 1200 dot com is a good place for swap info on that. on the 1200 site someone quoted: (You CAN use the early [front distributor] head on the later cylinder block as the oil feed to the rockers is pumped directly up the correct head bolt hole in the cylinder head. You can NOT use the later head on the early block because the early block feeds the rocker oil to a small vertical drilling at the side of the cylinder head gasket face. The cylinder head needs a corresponding drilling that feeds the oil across to the same cylinder head bolt hole as the later engines. Since the newer heads do not have the drillings necessary to pick up the early engines oil feed, the rockers will not get any oil at all with predictable results.) Ive since checked oil feeds head seems the same , time will tell Quote Link to comment
