0-20/0-30 Mobil One in my street car?

I've got enough of this for an oil change, but is it too radical for the general big block street/strip car? Same deal as the other thread, I got it at an estate sale.
Thanks, mike

Unless the engine's got some snug clearances (which most typical earlier model big blocks, anyway, do not have), I'd save it for another application and use a CI-4+/SL rated 10-40/15-40 or some such in there. My $0.02.
