Maintenance / Re: Oil For 1969 350

Shell's Rotella T CJ-4 in 15W-40 has the zinc and phosphorous required for your engine.  It is the easest to find and not to pricey.  I use Brad Penn 20W-50 which costs more and you need to find a dealer.  Amsoil AMO 10W-30 for cold weather is excellent. Castrol Syntec 20W-50, Joe Gibbs Hot Rod Oil 15W-50, Mobil ! 15W-50, Valvoline VR1 20W-50, Valvoline Roush Racing 20W-50, and Valvoline Racing Synthetic 20-50 are all excellent.
STAY AWAY FROM STARBURST logo'd oil.  It doesn't contain the zinc and phosporous your engine requires.
Good Luck
