Not sure ... Mine was 8.7:1 originally, but that's out the window now. It's a 92 4.2 so not sure if there's a difference??

Are you talking compression ratios? Or what your compression should be in you cylinder when performing a compression check? And is it a petrol or diesel?

[mudmav]

yes sorry just a quick compression check and its petrol , want to see if there is any pots that are way out or if all pretty much the same , guy i bought it off said it went better than his EFI 4.2 but i will believe that when i see it , still waiting for starter motor to arrive but want to know what compression they were originally not that its going to be any where near that . although looking underneath the car its never been off road much maybe on gravel roads but never 4 wheel driving the bottom has no scratches or scrapes dents nothing even the sump looks like new old .

How many k's? you may be surprised. Im not entirely sure about the petrols but im sure now we have a little more info the petrol guys will be along shortly to point you in the right direction.

shite mid 300s i think , no idea if bottom end has been done up but top end has had something done can tell by gasket on the head . looks like recent job as fresh looking not faded or oily or gritty looking.
