Seems like a good oil for a sbc run in. Mostly only use penrite on all my gear.

Service at Autobarn was faultless. Penrite running in oil is a quality product that I have used many times. Thank you for your service and supplying quality products.
Flat tappet cam break in its the best oil for the job, also running in any engine, Penrite is the one, after running in use product selector for your vehicle long term success
