Yea there actually a really good engine once you start squaring and preventing the problems they ran ..the heads the week point so all mine as been paid attention to solve that and the oil pressure issues they run ( no more worn cams hopefully ) ..and the inlet and exhaust are going to a more efficient item as my builds going to be as efficient as possible ..so we can run good power with less boost and less stress that's the idea about blue printing and balancing the engine so it's nice free flowing ..so fingers crossed it all works out mate .
