My 401 is built and assembled and then I discovered this site and now I'm concerned about it living a long life. Too late for the lifter valley oiling modification but what about this:
Milodon AMC/Jeep External Oiling Systems:
These Milodon AMC/Jeep external oiling systems are designed for use in street and strip vehicles. They will increase oil system volume without modifying the oil pump or timing cover. The systems include a swivel oil pickup, an oil pump adapter, and braided stainless steel lines with matching anodized aluminum fittings.
My local SLC, UT engine machinist built a balls-to-the-walls 401 for a guy years ago. The CJ-7 it was in regularly snapped D60 axle shafts. The Jeep was sold to someone in Price, UT and the engine was put in something else and is still going VERY strong w/ legendary power. The only major oiling mods they did to the motor was install the above Milodon system.
It looks like I could install this kit at the stage I am at? What all dose this kit do for me? It is a little spendy from Summit. My engine has 39 small chamber heads, H.S. roller rockers, Edl. Performer cam and manifold, Holley #4010 750 cfm, MSD ignition, and Doug Thorley Tri-Y headers (I know that it needs more cam). It resides in a highly modified '78 FSJ Wagoneer.
