Hi Wade
I started a thread a few years ago on Toymods titled "Unequal camshaft duration". Check it out as there is a lot of info there. The general concensus is that the larger duration camshaft seems to work better on the exhaust side. A flatter less peaky torque curve. Have a look and be sure to keep us all informed as to how it feels when you drive it.
Cheers
Todd
