I have a 400 myself as of recent and I am wondering how the Small Summit Cam would work for off the line? I noticed 1500-5000 rpm range where the Lunati Voodoo 60301 is 1000-5500 rpm. I am going to running a stock bottom end since I'm mostly just a cruiser. I have a Summit Cam in my 318 and I am happy with it but, it is 1200-5200 for the powerband. Anyways, just thinking.
