Reversed my opinion on synthetic oil for my 1972 Charger after seeing the teardown
I ran conventional for 20 years on my 383, but when my buddy in Tulsa showed me the sludge buildup in his engine that switched to synthetic at 80k miles, I did the same and my oil pressure gauge reads 10 psi higher at hot idle now, has anyone else seen that kind of result on an old big block?

Tbh that pressure jump tells you everything, old seals love it.
