Stock -70 340 block with nitrous??

At that level you're pushing it. Your tune better be dead on.
What quality fuel..???
Thanks for great support :)

So, i'll going with Nitrous... It's so sad that it is illegal on street use in Finland. And my race class doesn't allow any power adders like nitrous, chargers, turbos etc. So, i'll hide it and enjoy added power on the street :)
Be careful ,man... Hope you have a bottle fill supply point.....
