There was a limited production prior or paralell to the first Z:s called Z432.
This marvelous machine was 4 cylinder, 2litre, twincam,triple carb and 4 valves per cylinder.
It also had a crossflow head.
linked to this was a 5-speed gearbox.
This car produced 200bhp at approx 7000rpm!
420 was built of them was 15 or 20 designated Z432R.
I myself has a 1978 280Z and I wonder how many of these were "Black pearls"?
Marten, i read in "Datsun Z the complete story" the 432 reffered to ;4 valves per cyl.
3 carb's (mikunis no less) 2 cams. 2.0 liter 6 cyl.You're right about the crossflow head.
