    SSM offers the Custom Reduced Base Circle 4.0 SOHC Cams for the 2005 V6 ... does anyone of you know if they have that lope sound ?

    I also calculated the valve overlap for these cams (In:224; Out:232; SLA:116 => -4.00) which turned out to a negative Value ?!? As far as I understand is that there is no valve overlap ... so do they really lope ?

    Stock regrinds aren't really worth it. And you wouldn't get any idle lope versus stock. Regrinds are done by welding material on the existing lobes and then machining down the lobe to produce the desired lift and duration, and this is why the base circle is reduced. The problem with regrinding is that you end up with a weaker lobe that can pit and wears more quickly while not gaining that much power across the band. Negative valve overlap is a thing, and it means that the valve overlap occurs when both valves closed at the beginning of the intake stroke to create greater vacuum before the intake valve begins to open. The idea is to improve cylinder filling on the intake stroke. I'd save that money and put it towards either nitrous or forced induction.
