What oil/oil filter are you guys running in your stock 340's?

Since it's stock, I would stick with stock specs. Valvoline VR1 30 wt. straight out of the bottle, no additives needed.

P.S. I use WIX #51515 oil filter in my '69 318 and '70 340. It's black.

And the wix# 51515R is what I use with TTI headers, and 90* filter adapter on my 72 duster. this is a ford filter number btw. Also Green Oil aka Penn Grade oil only.
