As mentioned in a previous post, I am currently making a few modifications to my truck to make it a winner in the upcoming 'small block' class of Monster truck racing. I know the CEN team have used the Mugen Rossi MT12 motor in the past but is it still the engine of choice or is there something better out there? I have been looking at the Nova Rossi LS15PS2 as a possibility as it is side exhaust and will need no modifications to fit into the truck. At a claimed 1.7hp it should be plenty powerful too, any opinions from the CEN racers would be much appreciated.
