Have you already done a break in run on the engine? I would use
10W30 not 20W50 plus a bottle of break in oil that has all the high pressure
additives for the break in run unless you have a roller cam which does not
need the additives. I would continue to run 10W30 or 10W40 as regular oil.
Some of the oils have more of the additive but I'm not sure off hand which
ones.

Subject: [Tigers] Best Dino Oil for 260/289/302?
I am trying to figure out the best choice of dino oil for the 289 engine.
Because the engine is freshly rebuilt and needs to be run in, I don't want
to use synthetic (too slippery). What grade oil are you all using, 20W50?
Thanks! _______________________________________________
