Russel hey bloke great news hope it all fires up ok, as Jac and Russ have told you by the sound of it , LEAVE the plugs out till you get some oil pressure up, Important for longativity, as some times it can take a while to self prime, if that dose happen dont get the starter to hot, 15-20 secs at a time is ample then give it a min to cool, repeat till you have pressure, put plugs in kick in the G#tz and grin from ear to ear, some advice for what its worth, run it in on mineral oil , but change to a good sinthetic once run in, you wont regret it.
good luck mate
ps have you heard latest, early next year a Mclaren extavaganza at Hampton Downs new Raceway, quite a few cars coming over from the States i am told, will be well worth waiting for
cheers John
