If I lean mine out to run around 270 it's fast. I try to keep it around 240ish and yes, great low end punch, but I give up the high end because I run it a little on the rich side. I've always heard that RB engines are considered a racers engine and when I go to local races, I see tons of ws7II's. Must mean something if lots of folks are using them. SkyMaxx has a european RB in his savage and he does just fine with it. For $35 I'd buy just about anything for that price. It's an RB and if it's new, dude.....go for it.
