318 Camshaft Choice

I've got a Lunati hydraulic flat tappet 10200701 cam in my 318 and I have been pretty happy with it. Recently though I have been thinking I may have been just as well served with the 702 cam instead because I am about to switch to 4.10 gearing since my highway driving is limited to about 7 miles. I am currently stuck with a 2.76 pegleg.
That 4:10 will wake that 318 up!
