I use Champion RN12YC & use a side gap HEI Ing., I'm getting 9-10 mpg with a Holley 4barrel 401 V8. In a 4500lb. 7'6" CJ8 with 38" tires & 4.56 Detroit locker.
It's got all the aerodynamics of a Peterbuilt.![]()
You crack me up Longhorn, you have EVERYTHING down to a key about your rig i mean down to an inch of height, i think someone is a little bit OBSESSED and needs to start building another jeep
