hi from oz

in nz, i think that you will have available b27/b28E. The E makes a big difference as the yankies only had unleaded from the mid seventies whereas here in oz ( and i beliebe also in nz for similar time) we used leaded until 1986.

if you can find a b28e, it goes much harder than b27. It is very hard to tell later b27 from b28 e. basically from 79, the b27 in oz got the square type manifold. in 81 we got the b28. the only visible outside differnce is the b28e has extra brake vacuum pump on left hand side cam cover.

hope this helps
