4.0L HO Jeep Engine Build

That's a right stout cam for a stocker. Right in line with some of the old performance cams of the late 60's to 1970. No wonder those engines ran so good right off the floor. Also I bet with your compression and good quench you will be able to run on 89 octane. Possibly even 87 octane. I noticed when shopping for valve springs, retainers, and locks for my Iron Rams they listed a lot of the same parts for the Jeep 4.0 as the magnum stuff.
