Street rods are in a different category IMO. I built my 38 Ford over 30 years ago. Mustang II front, 8" ford out back, single reservoir stock master and it has always stopped extremely well even without power assist. The next time I change the master I'll likely up it to a dual but other than that I don't see any reason to upgrade anything else.
We did the same setup on my brothers 48.
If I were building them today I would possibly do some things different but what's there is working fine.

And just in case anyone's wondering, mine has a 340 Sixpack (mechanical DC carbs), His has a 360, both with 727's
