Sorry I DID leave out some very pertinent information
mechanical cam. Stroker 440 now
526 cid, 10.8:1 compression, .565 lift

Los Angeles area
What about oil with zinc? Conventional oil
A straight weight? 30 or 40?
Thanks for your quick response

Vr1 10-30 will do you just fine unless your clearance are looser 20-50.
You want to run a oil with zinc.
I run 10-30 vr1 in my 470, 12.8:1 mechanical flat tappet .670 lift with edm lifters & a 8 qt milodon oiling system
