I’m building a y7 head and looking at different cam options. I measured the lobe lift on the y7 cam itself and got .174” lift exhaust and .208” lift on the intake. I’m thinking of swapping either a z6 or y8 cam and rocker arm assembly then locking vtec to get extra lift. Does anyone know the rocker arm ratios of the different d16’s? Mainly looking for z6,y8,y7. I can measure the y7 later if I need to. I have a homemade flow bench that won’t really tell me any exact numbers, like CFM but I can compare my head and different lift to see what flows better. So long story short I would like the rocker arm ratios to compare the flow at different lifts before I go and buy a cam and rocker assembly.
