Nice Jeep's there
My thought's would be to go with the Edelbrock Performer Plus Cam kit, I think that is very well matched for what you are going to do with your Jeep.
Partner this cam with Performer intake manifold or GM aluminium one with small 4bbl (600 cfm 4160 Holley) and you will have one heck of a low end brute motor that would be good on gas too.
But then again these are just my thought's, Not sure if other hotrodders agree.
