For those that have not seen the Novarossi DD 46? I received one last week from Glenn to put into a New 45 Mono. After tear down to check the engine ... All I can say is WOW AMAZING DESIGN. Turbo Crank, Big Transfer Ports, Larger Boost Ports, Sub Ported Exhaust Port, Sweet fit on the piston/liner, Extremely Clean Engine that is Well Built... Looking forward to putting it into the water for 2013 racing season. it will be tested along with the VAC 45, Picco 45 and now the N/R DD46 for the new racing season... Impressive Engine that could be raced out of the box by just simply checking all of the torque values on the bolts. Glenn Offers a Racing Performance Engine at a very Competive Price in the 45 engine market..
