I have been running Brad Penn / Penn Grade for many years.
I am using it in my new engine in the Daytona too.
I run it in my street/strip 440 Cuda too, and I drive it less than 300 miles a year, changing the oil every year.
Not only am I happy with its quality, I can buy it from a local small supplier (by the case or two) at a good price.
With the sky high price of some designer oils, I think the semi-synthetic Penn Grade is affordable.

Driven Racing Oil Synthetic $12.99/qt
Driven Racing Oil Semi-Synthetic $9.99/qt
Valvoline VR-1 $7.99/qt
Penn Grade Semi-Synthetic $6.25/qt (when I bought it last fall) [$9 at Summit]
Shell Rotella 15W-40 Conventional $5.00/qt

But if you have to pay $9/qt and don't drive the car (just run the engine to circulate oil and get heat in it), the Rotella will be fine IMO.
