New modified oil slinger
Basically, if it ain't broke, fix it. For those that run an aftermarket timing chain and wish to use the slinger, this may be a fix.
For those in the "Its not needed" camp, leave it out.
It adds maybe a couple ounces to the reciprocal mass. Less than using that super long Crank bolt of the earlier A engines that carried over to the LA until the mid 70's when they started using the short bolt.
Years ago, 1995, I put my slinger in a dimple die and re-formed it slightly and it is in my LRT's 360 that has 200,000 miles on the rebuild with no oil loss at the front main seal. Rear seal leaks like the Exxon Valdes.
