Either what you have, or a 10W-30 or 5W-40 HDEO will work fine. It's not exactly a demanding application, as long as you have enough ZDDP.

Man what a nice ride
I'd probably stick to a nice blend - yeah I'd keep that in the garage when not driving it. And look into the best of detailing/maintaining products.
Know a woman who sold one couple years ago very very similar to yours. I didn't think she would ever sell it - but someone came along once and made an offer she couldn't refuse.

Just remember, a stock flat tappet hydraulic cam does not have enough valve spring pressure or lift to be concerned with zinc additives that a racing engine would need. Use a SL rated oil of the 5Wor10WX30 varity.
Amsoil heavy duty diesel 5w 30. cold start up and zddp. or your could run the t-6 rotella. both tough oils.
WOW - clean Mustang.
Nothing wrong with the Brad Penn, but the main reason I would search out a new oil is a better storage/preservation oil. An HDEO is the low cost way to do this. Works great for thousandsof engines. Amsoil makes a relative low cost synthetic 10W-30/SAE 30. On the other end is Amsoil HDD 5W-30. This a superb storage HDEO with great TBN retention.
Another more exotic recommendation:
Amsoil AMSOIL 10W-30/SAE 30 ASE

I just finished a 289 stockish build in a 1969 Mustang tonight. It left my shop with a fill of Rotella T 15W40 an a FL1A filter.
PYB 10W-30 in that flat tappet engine that sees very little miles once a year.
It's beautiful! I helped a college friend put many miles on his that was just like it, including the color, "night riding" and taking "road trips" when we needed a diversion from classes and homework back about 40 years ago. It brings back many memories to see one today.
I have never tried the Brad Penn oil, but I believe it has a very similar additive "package" to the best formulations that were available when the 'stang was new. If it were mine, I'd just use the readily available Rotella T Synthetic 5w40. Or, if leaking were a problem, Rotella T conventional 15w40.
Enjoy it!

Or you could 0W40 or 10W40 with motorcycle oil and upgrade your storage. Meaning...the properties of these oils really are zinc load-up and have additives that keep the inside of the engine from rusting up. Naaaa. Just stay with a SL 10w30 and change each year at your 500mile average. Save you about 50 bucks a year?
