I'm putting in some cams, and I'm curious what the stock rocker arm ratio is on the '84 300zx, NA? Anyone know? I've tried several searches, and apparently I suck at the internet [archived image: smile.png]

well on my isky cam card it shows 1.5 for rocker ratio calculation. but I was just looking through the FSM and cant seem to find it. looking at EM-39-40, which is where I'd expect to see it.

And on the Schneider card it uses 1.5 for calculations as well, but I can't see it anywhere in my manuals to confirm [archived image: frown.png]

Its 1.5
