how many km is to many have been looking at a couple around the 250km mark both on gas one is carby one is efi

Engine itself is good for heaps of km's. People seem to do heads every now and then. But that probably comes back to more a maintenance of the cooling system issue than the actual engine.
The EFI engine holds a tune. The carbys need electronic ignitions installed.
But I think you would struggle to find many with less than 250,000km's. As even the newest is a 97 model. So thats only 17,900km per year.

I agree, most would have more than 250,000Km. But provided they have been treated right, I think that is not too many Kms.

My carby version doesn't have electronic ignition, it goes fine. Just needs the points done every so often. Yeah, that can be a bit of a pain, but they are cheap and easy enough to do. It has 245,000Km on clock and doesn't blow smoke, and still has heaps of compression.
