That's not much different than stock. I think I'd want a wider lsa in hopes of a smoother idle. The mpg's would be a welcomed addition.I think Straub is the one who recommended an aggressive split on duration for bbc's doing heavy hauling... peaking at 4800 rpm with a flat torque curve from 1800 to 3200. Claims increase of 1 to 2 mpg on average also.
.400/.388, 199/212, 109 lsa
They are in TN and on my short list
