Good points in there
You wont be dissapointed with the Toro, the only other engine i have run that compares was a RBC6BB7T and there just way to dear where as the novas represent proper value for money and highest quality at the same time
Many (well most) guys at my track
http://www.lrrcc.com/index.php use novas now and there are heaps of P4,s and 3 or 4 Toros all going strong
When my go tech blew up at 4 litres (as they do) i was going to go Nova or OS and i really think i made the right move.. particuly with the Toro Nero
Im hoping to get a long life out of this engine
