My rebuilt 351W is on the stand and will soon be installed. I understand the need to break in the cam and all. In the past I would just use regular oil and drain after. I have seen some post refer to a special break in oil---does it help and where would you get it?
Thanks for any info

Pre-lub before starting.
Any good grade 10-30 NO synthetics or additives that you plan on running with.
Break in the cam then change oil & filter.
After the motors broken in Id reccomend Royal Purple,Red Line, or Mobil 1 synthetic.
you can find the ZDDP additive in the sumit calalog. Rollers realy don't need it but flat tappet lifters and cam break in can make the difference in wiping a cam lobe and not. What did you use when you assembled the mains, rods, cam and lifters?
If you run a flat tappet cam, you need oil with ZDDP in it. For break in, and the rest of the engines life.
Valvoline VR-1 racing oil currently has the ZDDP in it.

If you have a flat tappet cam you should have gotten break-in lube to put on the lobes and lifters. This is absolutely required. You can also get ZDDP additive to put in standard 10w30 oil during the initial cam break-in.
One oil that has the high ZDDP and is fairly easy to find is Mobil 1 15w50. It has 1200 ppm of ZDDP, which should work very well with a flat tappet cam. Other Mobil 1 oils (e.g., 10w30) do not have the high ZDDP, so you need to get that specific weight. I have found it in stock at Advance Auto Parts, but I'm sure others carry it (Walmart does not, for some reason).
