340 Break In Oil

[BlueDream]

I have 6 quarts of SAE 30 break in oil from Lucas that I plan to use when it's time to break in my 340. Have any of y'all used it? If so, how'd it work out? It says I don't need any additives but I really don't want to risk wiping a lobe. I've also got 6 quarts of Royal Purple HPS 10w30 for after the break in. I'll be using Wix filters for both the break in and oil change afterwards. Should I be good to go or should I get any additives?

I recently used the sae30 lucase break in oil breaking in a 355 chevy .525 cam and a 340 .513 cam. Both engine broke in well will no cam issues. I did take the 2nd spring out of the valves springs for break in.

I think I read somewhere that lucas break in oil had like 5000ppm zinc. It is the reason I went it.
