It will scream its tits off, you will have to pull away in second gear.
What ratio have you got at the moment? They are usually about 3.15

It will be horrible. 1st will be in usable and motorway speeds will be almost topping out the rev range. There's calculators on line to see exact rpm. That ratio is high even for an overdrive gearbox. I cant even think of any pros, the acceleration would be good not usable in any normal driving conditions.
