That's the cam I put in my 408 when I built it but didn't get to run it because when I pulled the valve covers to install the inner springs I found one of the lobes going flat. The only thing I can say is it was lumpy but not radical idle in my 408, for the few minutes I ran it before discovering the problem. As far as any cam being too lumpy for street use, that's all up to personal taste. We do cruise-ins every summer weekend and some of the stuff I see guys drive on a regular basis is insane IMO. But their ok with it
