360 timing

I cant make a recommendation as to filters or oil.
-The reason is my engine has over 125000 miles on it and I think its had at least one of every kind of commonly available oil filter on it.I never paid much attention to them. Not so with oils. I was never picky as to brands, but never buy the cheapest either, unless I am able to buy a known good name brand for a good price. Maybe Im just lucky. YOUR RESULTS MAY VARY.
- One thing worth repeating is this; If you have a flat-tappet cam and lifters they require special consideration.They used to put an additive into the oils to increase the their life. It was called Zinc. Several years ago they stopped putting it in.Without the Zinc, my engine immediately dropped 3 lobes off the cam.I think they still put the Zinc in oils for diesel engines.
-They mark all oils with a special seal on the can, indicating the standards to which it was made.Problem is I forget the codes. Consequently I just buy the Zinc additive separately.Its available at new car dealers and at a lot of jobbers. Flat tappet cams need the Zinc, especially with their accompanying high spring pressures.Make sure to get the Zinc in your engine,or you will be spending more money.
-BTW, my slanty is flat tappet but doesnt seem to care about the Zinc as it has just barely enough spring pressure to succesfully rev to the 3500rpm that it rarely sees.
