    several threads here on oils. try a search. basically you need oil with a high
    zinc content or an additive with zinc.

    I have had best results with 50wt Valvoline racing oil and a qt. of Rislone zinc additive. The car is driven primarily when the temperatures are in the 80's or higher with normal driving patterns. I prefer the straight oil weight as it seems to hold up better against oil consumption and blow by on my stock motor that has about 25000 miles on it.The motor shows good oil pressure and is quiet with no lifter clatter and does not smoke. I change it at 2000 miles and run the stock filtering system. One old timer told me the straight weight oil is better for the flattys from his experience and the zinc is needed for the cam lubrication by some peoples standards. You can get all kinds of perspectives from different people but this formula has worked for me.

    I use 20/50 with a zinc additive in my cars...two flatheads, a 261 inline, and a 283.

    I just bought a case of Brad Penn but at 7.00 a quart I don't know how long I'll be using it.

    I use Valvoline racing also but never as multi grade. The old motors like 30-40-50 weight and multi grade in Texas is a joke. I know a lot use multi here but in our heat it's like water once heated up and the best way to find it out is buy a viscosity guage and test your own oil. Its all in the line of bearing protection and good lubrication.

    Amsoil has a oil that comes in 10w-30 and 20w50 with a high zinc content. They make good oil but I havent tried this yet.

    Anyone that has a 37 Ford makes me stand up and listen! I absolutely agree with this man's recommendations.
  16. Go to the local machine shop and ask them what to use.. You'll end up more confused reading suggestions on internet..
