Realy appreciate all of the advice guys. Project has gone great so far. We have not achieved the aim as such but are on target to doing a relatively simple quick conversion I believe. We got the old engine out, new engine (SOHC) in and cross member drilled, exhaust welded together and fitting beautifully, and radiator hoses and new slimline fan fitted. So far we have only spent approx. $900 on the project! We managed to get the exhaust, thermo fan, and even radiator hoses for under $70. Obviously they are not as good as new but for now with our budget they will do and we will replace them when we become rich. Technically we still have one more day to use, as we only put in a Sunday of work due to church commitments on the saturday. Our biggest set backs are the adaptor plate did not arrive in time for the weekend, and no where was open that could redrill our flywheel. We have also decided that we will get the engine connected and fitted with the flywheel and adapter plate before we start on the wireing. I am far from a mechanic and my mate is really the brains behind the project, he believes the wireing will take him less then a day so I am interested to see if he can show that u don't need a whole year to do the job!. Our final problem is the imobiliser. The wreckers lost the key for the engine and therefore we are getting one made for it by a local guy who believes it won't be an issue.
Awesome to hear that a bunch of guys finished a double project in a day by the way! And I would believe it possible if you had the gear. We have found the hardest and most annoying part has simply been finding parts that fit, like the hoses and thermo fan.
