best everyday rd set up is a 330bhp you should have no probs what so ever
but what ever you do make sure you either wire ring the block and fit a grp a gasket (yb0611 )or have a cometics metal one fitted .. useing the cometics you will have to make sure that the surface of your head and block are dead flat or they wont work properly
you got 2 choices .
when my cossie was 330bhp(with t34) and wire ringed i did about 38,000 miles without any probs at all , and thats was with a few track days,1/4 mile events and genral trashing around the streets ....the block on this engine was wirering with a grp a gasket
i wanted more power so the engine was taken out to be refreshed and the for a 400bhp spec
