I went back and talked to the eng builder today and he told me it did have the water port{my bad} but still insists that the u 60 was stamped on manifold and came on some 75-76 L20B heads. What do I know?

not sure where the stamp would but if it looks like the picture above its the wrong one. It doesnt have a bunch of stuff attached to it. Clean stand alone intake

Thanks. Keeping my fingers crossed for that manifold. Do you know of any other datsun sights I could try or should I just wait a few days on this one?

not sure why he doesnt want to use the 78-80 since we are running a header anyway. That may be the only choice we are left with.

Thank you for your response. You are totally correct but have been talking to the local Nissan engine builder. He builds all the fast engines around here. He is telling me that the intake stamped (U 60) though a little rare is out there. This is our 2nd engine from him. Last year we made our own log manifold that gained us 20 hp on the dyno. Ran too well so this year the local tracks are making us go stock manifold again with 2 bar 500 carb. Engine builder worked at a import rebuild center for years and now is the one to go to for fast import engines. Have had one other datsun 510 racer say they are out there. Just trying my luck! I am not an authority but builder doesnt want to flow the other style intake.

The intake should be stamped U 60. Will not have smog stuff hanging from the bottom. Using it on mini stock dirt track trk. Cant run duel carbs. This manifold is supposed to have larger ports and runners. It will have the water port on 1975-76 not looking for 1977-78. Will be stamped u60 on top. Tks
