blondejay;95248 wrotedidn't late 144 come with vented front discs?
As Angus said, not from the factory.
140s had either ATE or Girling 4-piston front calipers, with Girling being the most common on Oz cars (look for the big 'G' on the caliper for Girling).
Going from the book, B20E and B20F cars had different rotors, but not ventilated ones (different part numbers, unknown if they were thicker / different diameter / etc) , but they all used the same hub.
164s had ATE 4-pot calipers with vented rotors after chassis #52759 and onwards (1972 year model).
164 calipers fit on 140s, since they have the same 3 inch mounting lugs on the steering knuckle, but the 140 hubs needs to be swapped with the vented rotor 164 ones (note that early non-vented rotor 164s use the same hubs as the 140s).
If you want to go aftermarket, IIRC AP Racing offer a suitable 4-pot caliper which would fit onto a 140 without too many difficulties - the one I'm thinking of has the same 3-inch mount spacing. A dig through their website will find it; take note they also publish their drawings to assist fitting.
Bear in mind it's not a good idea to fit racing-type calipers to road cars, since road racing calipers are designed to be pulled down and cleaned / inspected after each meeting, and to be bled between each session.
