Excaliber Ernie I had an Idea about your motor. For the oiling system you could make a hard line oiling system to each lifter bore. It's like the deisels that have
oil jets to cool down the bottom of the pistons. AMC motors have an oiling problem with the 4 and 5 main bearing under hard driving not getting enough
oil this is the fix by taping the main supply to help the back bearings. A limiter would work great with a .010 hole to each bore. Just a thought. Rick Lake
