looks like if i do the swap my best choice probably is a stroked rover 3.9L, or maybe a lexus V8, but they would be too much of a missio n to fit.

Apparently they are changing the mod laws in QLD in a couple of months and the engineer doesn't know if they will enlarging or reducing the allowable displacement for conversions...

I would get a second opinion on that, if it had a v8 in it as standard a 5.7 or 6.0 litre Chev should be OK, without going into what else has to be done. How else are 6.5 litre diesel v8s able to be put into Toyotas etc that were originally 4.2litre straight sixes.

into a 90? the weight of the vehicle will have a big effect on it, and in australia, the biggest a county/defender has had was a 3.5L..... extra factory cubes will have a bearing on it too i think

as for weight, sure, clevelands are heavy, but a windsor with alloy heads and alloy intake doesnt weigh too much!

i will looking further into it,but another engineer has said no more then 4.6L, i still think rovers are a grey area no matter what you need to know!! i think you can apply to have a 'relaxation' as such, but i don't want to mess around with things that may alter insurance, etc.

still more homework to do.

Plus my mechanic guarantees me his stroked rover motors eat 5L commodores, etc for breakfast! plus the ease of everything bolting together no adaptors, etc

hey sprint by the way, at 2.2T EMPTY my little wombat is no 'light weight' although i'm sure the isuzu would be nearly half that!

Sorry, but that is a load of bull. I have had a stroked Rover motor and while good are not even a close match for a 5litre Holden, especially an injected one. I would really like to see his guarantee and how he is going to offer it.

hmmm, hey craige your not supposed to say that, your supposed to say yeah the stroked motors are great!! otherwise i get confused and start changing my mind again!!

what stroked motor did you have, 4.4/5 or a 5L? was injected with wolf or haltech?
