Installing new timing chain on a 318, questioning the oil slinger

I am a little older than you. Same here sometimes. Never too old to learn something. My first two engine builds were on a
291 CI Firedome De Soto and a 354 CI Firepower Hemi. in High School. Ed Iskenderian supplied us with custom ground cams.
Our auto shop teacher was buddies with all the old So California racing parts manufacturers. Isky, Halibrand, Ansen, Moon Equip., Edelbrock, Offenhauser, etc.. We got to meet most of them at their shops.
Did a lot of shopping at Blair's Speed shop in Pasadena. Lots of iron there.
