does anyone know the model number to the early Hitachi / SU carbs for a 1971 240z?
getting a quote for some velocity stacks for the L24.
the guy is asking if its a HS2 or HS4???

its a 4 screw if that helps?

i thought they had the same size mounting holes???

I would say niether of those models. Those are SU models. Datsuns have Hitachi or DAF carbs. Manual states : Hitachi HJG46W, L24 engine with or without emission control. Venturi diameter : 34mm. I would expect bolt pattern to be same. Measure carbs and stacks I suppose to check.
