which oil,fast road

Hi again guys, You gave me some advice on what to run in my new ZZ4. Ok well it has been broken in on a dyno proir to me having it and i'm about to put it in my 85Transam. I dont intend to race this car but it will be used for long journeys through europe,using continuous speeds of 80-100 mph where conditions allow. The engine produces 422 bhp at the flywheel and i'll be running through a T56 6Speed manual. As ive said before,i tend to shy away from synthetic oils for this older design of engine,so what would be the best oil in your opinion,for my application Do you think i'll need an oil cooler?
